I borrowed this pic from @http://www.914world.com/bbs2/index.php?showuser=26993 in another topic. Does anyone know where to buy the hoses like this? I have seen and tried others but they have issues and I wanted to try these.

Posted by: brant Feb 21 2023, 11:22 AM

watching this thread... I need one too.

914rubber I believe. I bought some last year. Excellent stuff. Way more than I needed.

Posted by: NARP74 Feb 21 2023, 11:31 AM

Tried that it was very flexible and moved around a lot, especially the long side. I have heard that the longer hose can get sucked in to the engine cooling fan if it is not supported somehow in the middle.

Correct there is an actual OE clamp that doesn't show up on the 914 PET but mounts to the center top of the impeller shroud to prevent

Posted by: GregAmy Feb 21 2023, 01:07 PM

I tie-wrapped mine to a small bracket inserted under a fastending bolt at the top of the fan housing. Plus I run one of those bus Type 4 screens in front of the fan. I'm running the 914 rubber hoses.

"If you've tried others" and didn't like them, you might wanna let us know, otherwise we could be rcommending teh same ones...

Posted by: NARP74 Feb 21 2023, 01:23 PM

As stated in the 1st post, I am looking for these specifically. I have tried the 914rubber ones and found them too floppy for me and I did not like the crushing that happens when you attach the clamp to either end of the connection. Others sell the same ones. These appear to be a harder plastic with formed ends for the clamps.

Posted by: 930cabman Feb 21 2023, 01:31 PM

NAPA has it, found it there last year, fit perfect. If I recall it's called "defroster hose"

Posted by: 914werke Feb 21 2023, 01:32 PM

If found no one presently selling hoses that are true to the OE design ....for a long while.
How Ive remedied the "floppiness" of the long hose particularly, is to insert a paper/foil hose of slightly smaller dimension inside the hose.
It also solves the problem of perforated 50 yr old OE hose.

Posted by: wonkipop Feb 21 2023, 04:37 PM

ok

i've dealt with this problem.
30 years ago, much to my horror, the guys who performed all the rhd conversion engineering and approval work on my car split my original short lhs heater blower hose in half to extend the system across so it used the rhs side. this was because certifying engineer would only accept the defrosting bias if it was switched.

i reinstated the original set up as soon as i had the car registered and on the road.
but i was left with a beautiful original hose that had been in perfect condition that had been cut in half.

i went to a mercedes parts guy back then in perth and was able to find an almost identical heater hose that he supplied. it was 65mm in diameter. i sleeved it over the two ends of my original heater hose and let the ripples in both hoses contact with each other for a binding fit. at least that was the theory. but it proved a little too loose and would always work its way loose.

so more recently i tracked down some Eberspacher ducting. used for caravan/camper van heating and a/c systems. its 60mm diam. i cut a length of this and sleeved it very tightly over the existing two ends of original hose. this let me use the end sections with the original clamps for a good fit to the blower and the engine tin. its been a good binding fit to the original hose halfs and has not worked its way loose.
this hose is fantastic. almost indistinguisable from original. it bends to shape but retains shape it is bent to. its perfect. i am sure you can fit it directly to blower fan and engine tin without fussing the simulation of the factory part like i did.

eventually i notice most original factory heater blower hoses bite the dust and develop splits anyway by this point in time.

https://www.caravanrvcamping.com.au/airtronic-60mm-outlet-kit





airtronic ducting i now have on left. 60mm diam.
mercedes benz ducting i had used on right. 65mm diam.




how it looks in engine bay.
nice semi rigid ducting that holds to the shape you bend it to.




as to the extended heater hose that you see on some 74 and 75 cars and the duct splitter that lets you do the two hoses, the reason its not in the PET is i believe it was not offered by the factory for the 914s. i think dealers worked out they could use the twin hose set up that was on VW 411/412 variant/squarebacks. that particular type 4 sedan had a fan that was squeezed over in the space on the left hand side of engine bay. it used the same fan as used on the later 914s with the extra attachment to do the duct split and the long hose to get across the engine as well as the short hose. also had the clip to hold the hose over the fan casting. you can find all the bits in the type 411/412 parts catalogue with the part numbers. go to VW classic website germany. but can you still buy the parts? i don't think so. you might find them in a wrecking yard on an old VW 411/412.
it will be on the squarebacks only. the sedans had the other type of fan that was on earlier 914s with the two outlets either side.

Posted by: wonkipop Feb 21 2023, 05:35 PM

here is page from 411/412 parts catalogue.
had it filed away.

the original mod, whether by dealer or by owners back in the day, was sourcing parts from VW book. you can see all the bits. duct splitter. the stand off clamp. though i was wrong about attaching it to cooling fan casting in 412 variant. variant used the standoff clamp to hang the motor from underside of top of engine bay sheetmetal. for 914s they just used the clamp to support the hose and fixed it to one of the nuts on the fan casting. and they used the long hose.

none of this is there in 914 PET. all it lists is "additional blower" (ie later blower) and one short length of duct at 450mm. the only thing special to the 914 was it did use a transition piece out of the variant fan that was rectangular to circular for the single circular hose.

The one pictured looks just like the one I just got from Auto Atlanta.

Posted by: NARP74 Feb 21 2023, 05:46 PM

Maybe it is NLA, but the hose I saw there looked just like the 914rubber hose. Maybe I am not using the search term for the desired results.

Got a link or part number?

Posted by: wonkipop Feb 21 2023, 05:58 PM

i just had a look.
you are correct @http://www.914world.com/bbs2/index.php?showuser=24549 .

it looks like AA has same type of long hose as 914 rubber.

i looked at listed part for original short hose for a 74/75.
pictured ducting looks to be exactly like Escherbacher hose i posted above that i got hold of here.

neither have the smooth flat section at ends for clamps.

although it does say on the long hose one that AA has, they also offer factory originals.
i guess these must be good condition second hand parts.
probably at a premium price as its a very difficult to get item now.

if all else fails - and presuming you can find one in a junkyard, you could get hold of an old poor condition 914 heater hose. assuming the end sections are still good.
and do my trick of threading them into a sleeve fit with escherbacher duct.
so long as you have enough original section, long enough to get a good sleeve fit it could work very well and look almost factory. take a sharp eye to spot the difference. the original heater hose almost has to be screw turned into the e. duct hose so its very secure as a sleeve fit.


EDIT
i think i can see why 914 rubber and AA would have that different type of non original looking hose. don't know for sure because i have not seen it in flesh but it looks like its very compressible. = small package for postage/freight.

the e. hose duct i got hold of is semi rigid. does not compress to any real degree.
package would be very long to freight it. $ could be reason.
i sourced my e duct locally in the city i live in down here. freight was of no consequence. i just went to the store and got hold of some.
might have had a reasonably hefty freight charge otherwise. would need to be protected by packing to prevent it being crushed.

Posted by: NARP74 Feb 21 2023, 06:02 PM

I'll ask some of my sources to see what they may have.

As I start to measure things the connector on the fan is 55mm and the 914rubber/AA hoses are 64mm or a little over 2 inch and 2.5 inch for the hose others sell.

Posted by: wonkipop Feb 21 2023, 06:14 PM

correct.

and 64mm diam hose is too big.
i know that from earlier experiment with mercedes duct.

60mm e. duct will just fit around the original duct.
just.
you have to screw the original duct in slowly bit by bit.
i think i might have lubricated the original duct with a bit of dishwashing liquid which helped me get the new duct on. in my case i literally used the entire original duct.
both halfs that i had i screwed entirely inside the outer sleeve of 60mm e. duct.

you could easily make a long duct out of surgery on an old original short duct by doing much the same thing.

The complete fan blower assembly and hoses are missing on my car. What is the purpose of this blower assembly?

Posted by: NARP74 Feb 21 2023, 06:51 PM

It provides heat through the exchangers on the exhaust if you have them, then up the longs and to the diverters and blower up front for the cabin etc.

Posted by: wonkipop Feb 21 2023, 07:50 PM

to the best of my knowledge its only on the 4s.
the sixes use bleed off the cooling fan?

Posted by: wonkipop Feb 21 2023, 09:38 PM

dunno about chevs, but you'd be surprised what comes off a Ford that can fit on a Renault. or off a SAAB on a Renault.
so.........maybe its true.
if this magical defroster hose exists I wanna know the details too.

Posted by: bludden Feb 21 2023, 09:43 PM

I got my car with the fan not installed, and no hoses. So I got the hose kit from 914rubber.

Pros: Easy to use fits well. Seems to do it's job.

Cons: easy for an errant tool to rip the material.

Posted by: Jett Feb 21 2023, 10:04 PM

The initial OE hose is NLA and most of the old ones are cracked. As 914Werke shared we inserted a paper hose and put the OE back on.

While restoring our 73 and 75, we ended up buying every likely related hose from Porsche, 914Rubber, AA, Pelican, Stoddard, and ECS. The only two OE “air” hoses that we could not purchase were the engine bay hose (being discussed) and the longer passenger dash vent to frunk paper hose (short versions below).

For our 73 2.0 build, a VERY kind member ( @http://www.914world.com/bbs2/index.php?showuser=13687 ) had saved an NOS engine bay hose for many years and then gifted it to the car . Every time an enthusiast sees the car I share the story.

In that spirit, @http://www.914world.com/bbs2/index.php?showuser=24549 please send a PM and we’ll see if there is something in our box of hoses that you can use.

I feel like Veruca Salt in Charlie and the Chocolate Factory, "I want that one and I want it now"! I am not in a hurry, but my mind latched onto those hoses as the absolute perfect combination of form and function and anything else looks inferior. It might prove to be a fools errand but I will keep looking and I appreciate the commentary and involvement. Keep it coming...

So are the hoses in the pic the original hoses? NLA it seems

The bughaus hose at least has the proper ID, 55mm, I will look at those some more.

I also found these but need more info on them.

@http://www.914world.com/bbs2/index.php?showuser=17686 I'll send you a note. Thank you

Part numbers I have found so far, but these are from a PET that shows the dual outlet fan motor, not the split adapter;

But the axles are fine.

They might look correct, but I wanted real heat. Bought caps and SS clamps at the hardware store plumbing section for the J tubes. My fan lives on a shelve in my shed.

Not sure if I can provide a link, but I did save the label, tomorrow I will get into the shop and find it. I tried several sources and NAPA several times until I found store manager who would go out of his way. Seems like a simple part, but it nearly kicked my butt

Posted by: dr914@autoatlanta.com Feb 22 2023, 03:15 PM

we have plenty, early cars 70-72 use dissimilar sized ones, 73 - 12/74 cars use a single short one, 75.5-72 use similar diameter long and short ones.

We also make the branch to convert the single hose 73-12/75 to the dual blower nozzle set up

use one short

Posted by: wonkipop Feb 22 2023, 03:40 PM

can understand completely.

i went into this 5 years ago in what became a slightly obsessive quest to replace my original 74 single outlet hose. i wasn't going to give up. thinking-----its a VW part right, so i should be able to track one down somewhere? no luck - even armed with the right part #s and searching VW vintage parts suppliers etc.

however i did have to trawl my way through the PET and associated VW parts catalogues like you are now. i was initially puzzled by that listing of the 920L hose as right side for early cars. 914/4 means early cars in PET. later are listed as 914/1.7 or 914/1.8.

i drew a couple of conclusions.

1. the PET is misleading/incorrect. not the first time either. i have found numerous errors and blanks in the PET when it comes to the 74 1.8s.

those hose numbers and descriptions are definitely incorrect for the early twin outlet fan cars. the R hose is 520mm long. the L hand hose is 420 Long. the hoses originally came from the VW parts bin and are for the 411/412 sedan blower hose setup.

however that 960mm long hose is the one you are looking for to do the right hand side twin hose set up for the later single hose fan despite it being mistakenly identified for early twin outlet fan cars. either that or VW were cutting them down in length to install in 914s.

2. they couldn't even be bothered drawing the single hose fan set up to update the PET.
it applies to the 73 models on. all the bits are just lumped as a group at the end of the parts list details. no key numbers back to the diagram because no diagram.
they list two different hoses there with basically the same part number. that means the design/construction of the part was superseded. somehow they altered the way they made the hose. but there was only ever one hose and a single outlet fan from 73 on.
anything with two hoses from 73 on is an owner mod or a dealer mod post factory.
with parts coming from VW parts bin.





and here is the VW parts bin.
from 411/412 parts catalogue.
i found this stuff years ago and its proved to be a handy resource at times as an alternative route to track down bits for the 914.
VW germany host the site, its part of the business empire.
generally however VW germany are useless in terms of classic parts supply.

https://www.volkswagen-classic-parts.com/catalogues/Typ4/html5.html#/14






you can see there were 4 different hose lengths used by VW.
and only 4.
the 960 L hose listed in 914 PET agrees with the 960 L hose listed for the 411/412 variant - same part number. for the variant they used a short 300 and a long 960.

----

the 914 PET is misleading as it mistakenly puts that 960L hose in there for the early cars when it should list it as a 520.
however despite the mistake, the 960L hose is the one the mod was done with for later post 73 cars. its easy to check. just put a tape measure in the engine bay.


-----

all the different hoses in the cars that Porsche were using as their parts bin.




and the dimensions given for hose diameters are amusing.
the twin outlet fans appear to have used a 55mm diam on LHS and a 60mm diam on RHS.
the single outlet fans used a 55mm diam hose both sides (or if you read the VW catalogue the dim is 55.5mm diam. germans! going to a decimal point!!!

anyway. good luck.
if you find out where to get these hoses let me know.
i will want to get hold of one.
i am happy enough with my make do effort at the moment, but i'd be happier with the real thing. it still grates on me what the guys did 30 years ago cutting it into two pieces and taping an extension hose in between. sometimes mechanics just do the stoopidist things.

Posted by: wonkipop Feb 22 2023, 04:04 PM

i also remember i developed a view on this change to a single outlet fan from 73 onwards. because i used to think it was just porsche being cheap skates trying to cut the cost of the car down to the point where they were counting 5 cents worth of hose.


it was all part of the horror of vapor lock i think.

they fiddled around slightly with the FOOL pump location in around 73.
moved it very slightly under the car.
and what i think they did was decide not to channel so much heated air through the hose connection into the long on the right hand side. its right near the FOOL pump revised location.

it still wasn't enough. the horror of vapor lock continued.
there was a dealer mod that jeff bowlsby has on his site involving a lash up duct to direct heated air out of the dump valve on the rhs heater flap box under the car.

then in 75 they bit the bullet and moved the pump up front and it became a fuel pump again. only now they had the charcoal cannister next to the battery crowding the 1.8 relays and resistors etc because the EGR had to go somewhere and the good location they had it in for 74 was no longer good. so now the cannister got in the way of doing a dual outlet fan. got pretty crowded down there. so the single outlet fan stayed.

along with the biased heating and defrost.

which caused a brain fade moment in australia 30 years ago where a couple of guys cut a part made of unobtanium in half to satisfy a road safety certification "expert".
i remember saying to the expert at the time, listen mate, i never drive this thing with the top on, when em i gunna need a demister.

Posted by: NARP74 Feb 22 2023, 04:04 PM

WOW @http://www.914world.com/bbs2/index.php?showuser=24231 you got way further than I did! Thanks for the great research. It does seem like the documentation got a little lax toward the later years, maybe they knew it was ending or the crew was working on other projects and did not care to backtrack the last few years. I have been befuddled by the PET many times.
We are spoiled I guess. So many parts are available in the aftermarket it surprises and annoys me when something is not.
I'll keep going.

Posted by: wonkipop Feb 22 2023, 04:17 PM

believe me i don't want to have to do this research most of the time.

but........if you own a 74 1.8 what you realise is it was chaos in the second half of 73 as they were trying to bring the 1.8 to the showroom.

the EPA was down VW's throat over an emission scandal and they were really struggling to get the L jet system out of the end of the production line.

this chaos is reflected in the PET catalogue and even in parts of the factory workshop manual.

anyway, all my research didn't do me any good. still couldn't source a fricken heater hose.

Posted by: NARP74 Feb 22 2023, 04:24 PM

Cheers, I get it. I have gone down these rabbit holes a few times now hoping for a miracle save at the end only to fizzle out and be left hanging empty handed. Oh well...

Posted by: wonkipop Feb 22 2023, 04:33 PM

interesting observation by dr. 914 of auto atlanta.

about mid 75 cars on getting the twin hose set up.
the dr. would know. his chronology is likely 100% correct.

that may have been the case. i'm down here and there is only really a handful of 914s in north antarctica so i don't really see first hand what various reliable examples were.

certainly i have seen various 75 1.8s that had the single fan and hose as part of our L jet research from a couple of years ago.

again the PET does not reflect this. typical really of the PET.
i'd trust dr.914 over the PET on this type of stuff.


EDIT
had a quick scan through the stuff i had on file for 75 L jets.
after looking closely my file agrees with the doctor.
all the ones with vin stickers up to 12/74 are single hose. (most cars have split orig hoses or aftermarket replacement).
all the ones with vins after 12/74 have twin hoses with twin tube transition.
hoses in similar condition. anything original was split around the corrugations.

so much for the PET!

i recall now i even looked for them in south africa. SA had its own VW plant and made 411/412s for the domestic market there. couldn't even track them down with VW parts suppliers there armed with the VW part numbers. searched all the classic bus websites because they had the same fans and ducts. all they had were the corrugated card with aluminium lining aftermarket hoses. i even tried porsche australia because i knew the 912E had them too but the lengths would have been wrong. narthing with them. all they could offer were the corrugated cardboard type heater hoses that the 911s use.

Dug through a pile of 2022 receipts and found NAPA P/N NOE 813-1509. All for less than 6 bucks and long enough for both sides

https://www.napaonline.com/en/p/NOE8131509?impressionRank=1

Hard to tell from pics but it looks close. 2.25" is 57mm, so close to 55mm, probably close enough to seal with the proper clamp. Worth a closer look. Dorman makes it, 96003. https://www.dormanproducts.com/p-28304-96003.aspx

Thanks @http://www.914world.com/bbs2/index.php?showuser=24877

Posted by: wonkipop Feb 22 2023, 06:44 PM

pretty close.
better than 60mm.
i think with the originals the 55mm might be referring to the diameters at the ends where they clamped on. those ends were smooth non corrugated sections for the clamp specially moulded to be all one piece. so i think 57 ought to work!
nitrile rubber construction. whats it like @http://www.914world.com/bbs2/index.php?showuser=24877 . does it flop around or is it rigid enough. one things for sure. it would likely be more durable than the original plastic ones.

nice.

i believe we now have NAPA stores here in north antarctica.
might have to enquire.

Posted by: NARP74 Feb 22 2023, 07:34 PM

I agree @http://www.914world.com/bbs2/index.php?showuser=24231 I'll go by one in the next day or two and try to get some and check it out.

Thanks brother!

@http://www.914world.com/bbs2/index.php?showuser=24231 can you spare me a trip out to the garage to uncover the engine and comfirm what size we need for our single hose 74?

Posted by: wonkipop Feb 22 2023, 09:20 PM

you are gunna love this.

according to PET it should be 460mm long.
but i made the sleeve exactly to sleeve over the two halves.
and mine is 520mm long.
EDIT i double checked - i am measuring it in car bending tape around so it kind of stretches a bit. the tube that is. being corrugated. but i'd say that is what it is.

i don't know what PET determines is a length measurement.
but its 520 long for the original hose that was on my car.

55mm diam cause it sleeves inside a 60mm diam tight.
@http://www.914world.com/bbs2/index.php?showuser=24549 has that bit right.
so 57 should be good.

Posted by: Van B Feb 22 2023, 09:26 PM

Thank you kind sir. As much as I like the aluminum lined hose, I think what @http://www.914world.com/bbs2/index.php?showuser=24877 found will have the best durability in the long run.

Posted by: wonkipop Feb 22 2023, 09:33 PM

i think it will be better.
though its good if its at least semi rigid and not too floppy.
i will give it to PET on length measurement because since is accordian hose it can sort of stretch as it changes doing curves etc.
PET length is probably compressed length. doesn't stretch much but fitted probably takes on a different dim.
buy enough to trim down later to suit your artistic whims when installing.

I bought a 75-76 splitter for the fan on my 74. I have the hose going across the front, above the fan shroud. I actually tucked it behind the hose going from the oil breather to the air cleaner, which keeps it away from the cooling fan inlet.

I have the paper hose that Automotion used to sell. I did this years and years ago, obviously, and am not sure about a modern source for the hose. But I wouldn't be surprised if Aircraft Spruce didn't carry something.

Realized I posted the wrong hose. Here is the 55mm version.

I bought that Dorman 96003 last year to replace my hose and it worked great. Used the original clamps. Actually have a pretty long section of it left after I used what I needed.

Its nothing really special & could easily be duplicated.
Id take a pic but its installed on my car & not much detail can be had.

Posted by: NARP74 Feb 24 2023, 12:35 PM

I've never seen one. If anyone has a pic of the holding bracket for the longer hose you can share that would be great. I have some easy cheap ideas but a starting point would be nice.

Posted by: Mikey914 Feb 24 2023, 01:51 PM

Funny thing is we have 2 camps her. The OEM hose is paper. I would use it if it were concours. The latter is just trying to find a hose that fit.

We can help you out on the 2nd camp

We have been selling a more durable hose for years in 2 options. The aircraft hose got very expensive but was best. We have a 2nd alternative that is more durable than paper, but if your worried about damaging hose it's much better that the paper and aluminum.

Posted by: NARP74 Feb 24 2023, 01:59 PM

The really cool part would be a short connector that threaded into the windings of the hose for each end that also had a smaller ID and was flat for the band clamp to sit in and not have to crush the hose down several mm to make a tight seal.

This one time, at band clamp...

So my mid year 1973 914 2.0 came from the west coast to me in NH sans everything from the heat exchangers on up. I would like to put it back to original and will be in need of a complete setup and would prefer not having to piecemeal one together from bits and pieces. Far fetched perhaps but obviously not all feel the need for heat/defrost capability , witness all the cars running headers sans the exchanger sheetmetal. Let the unicorn hunt begin.

@http://www.914world.com/bbs2/index.php?showuser=24231 posted the PET info earlier in the post for more info. Some of the parts are easier to find than others, lots of them are available from our favorite vendors on this site. I don't think a kit exists except maybe from a private hoarder.

Posted by: 914werke Feb 24 2023, 04:30 PM

That is innacurate. The OE hose(s) were plastic accordion pleated with 22mm straight sections at either end where they were slip fit over & clamped to the J-tubes.

I ordered some of the napa/dorman hose, should be in on Monday. No stock of any size to even look at.

Posted by: malcolm2 Feb 26 2023, 08:49 AM

Maybe my fan was just crappy.... But I installed the fan and the hoses. Pull the heat lever up to activate the fan and I can feel the flow, but it is kinda like the breeze you get from a screen door closing.

Not worth the amount of time or space it takes up in the engine bay.

So I just use my foot at a stop light and get up to about 2000 rpm and stay warm.

Does anyone find this fan option even works?

Posted by: GregAmy Feb 26 2023, 08:58 AM

Works fine for me in my '74. I have to turn it down/off at times, even.

Sounds like you may have some air leaks.

Posted by: NARP74 Feb 26 2023, 09:02 AM

@http://www.914world.com/bbs2/index.php?showuser=13139 Both types of older hoses can crack, get dented or leak over time and many repairs and hands touching them. You might need to do a quick review of the system, follow the hoses. I had a big hole in the tube under the speaker I did not see for a while. You can take the hose off the blower in the engine bay and see how it is working, mine moves a lot of air.

Posted by: malcolm2 Feb 26 2023, 11:04 AM

i must have had a weak fan. Hoses were new and operational, fan was purchased used from here, and it did turn. whole car had been taken apart and re-worked, no holes in the threshold pipes either.

Wonder what kinda flow is normal.

Posted by: wonkipop Feb 26 2023, 11:58 AM

gale force 2.
heaps.
sh#tload of air.
etc.

somethings up with yours.

as you pull the heater lever on the floor up, you should be opening the flaps in the heater boxes at the front end of the heat exchangers gradually more and more. cable operated from lever. this lets the hot air from the heat exchangers through and up the longs. its not until you pull the lever fully up that the fan kicks in. its a boost fan for low revs. like sitting at the lights. normally at higher revs cruising the engine cooling fan which is also connected to the system is providing sufficient air flow to push the air through the h e s and with the lever partly up to open the flapper valves to heat the car. the air flow from the cooling fan comes off two little valves with flaps the are off the side of the cooling fan casting on the underside and join to the h e.

not all type 4s had this engine bay boost fan.
i've seen a couple of south african 411s years ago that were in australia.
did not have the engine bay fan. hot climate car delete?

Posted by: skota23 Feb 27 2023, 01:09 PM

I think what I've learned here is that my hose is special and I should be gentle with it.

Posted by: NARP74 Mar 4 2023, 01:15 PM

Sorry to reopen this, hopefully we don't get to 6 pages! Did anyone ever find a part number for the bracket? How do you get a part number for something not in the PET?

Posted by: wonkipop Mar 4 2023, 05:17 PM

go to page 2 of this topic.
i posted up the pages from VW 411/412 parts book.
its there. you can see it in illustration its a VW part. shared with 914 or borrowed for 914. they seem to have just used the circular strap and not the T hanger that went with it on the 411/412. but you won't find it. no aftermarket for 411/412 and no VW spare parts for 35+ years. except in a junkyard.

i hope this doesn't flick it over to 6 pages...........!!!!!

i would suggest what is called a stand off clip or stand off bracket.
commonly available from specialist plumbing suppliers.
used to hang fire services pipes in buildings or other plumbing pipes which have to be stood off surfaces a precise dimension. often they have separate adjustable ht t fixing brackets that clip screw or bolt to the circular pipe strap.
look them up on google.

ie this.

https://www.bunnings.com.au/kinetic-50mm-head-pipe-saddle-clips-2-pack_p4920109

a spacer fitted between where you bolt fix it will let you adjust overall inner diam to suit hose. the one i have linked to is pretty close 50mm.

Posted by: 930cabman Mar 6 2023, 05:51 AM

Did the NAPA/Dorman hose show up? and working ok

Posted by: NARP74 Mar 6 2023, 09:42 AM

Picked the hose up. Looks like it will work fine. Smaller ID is a bonus over what the usual sellers have, 2.25 v 2.5. It is spiral wound v accordion in case any one was asking. The larger hose is harder to mash down with the clamp to get a good seal, not critical in this case but it helps. I have not installed it yet, I will need a clamp to keep the longer hose out of the engine fan, especially after the engine warms up and the hose gets more flexy. It should work fine and look good too.

Having said all that, I still prefer an accordion style hose that is more rubber than plastic and a little more rigid. Still looking for perfection for a crappy old race car. Make it make sense...

@http://www.914world.com/bbs2/index.php?showuser=24549 how did that NARPA hose work out? Same result as @http://www.914world.com/bbs2/index.php?showuser=24877







And yes… I know exactly what I’ve done

Posted by: NARP74 Mar 15 2023, 08:34 AM

That's hilarious, you will suffer the wrath though... I was waiting for someone else to do it!
I have not installed the hose yet, I am looking for a suitable support hook for the middle of the long hose. The NARPA hose is a smaller ID and will be a better fit than the other options I have purchased blindly online. It is a tight fit on both the single and dual outlet connectors and should be just as good on the lower connection as well, just haven't tried it yet.
My only complaint, and this goes back to the original question is that the spiral wound hose seems to be more flexible and need more support due to material and construction. The accordion type, as some else called it, uses more substantial material, plastic or a heavy rubber even. I have a short piece of hose in a parts stash I found that is different than the one in the first pic, but would be perfect. No idea where it is from or what it is for. It almost supports itself , looks good, had no ridges at the connection ends and was made to last in a hot environment unlike the plastic original ones.

Posted by: NARP74 Mar 15 2023, 08:38 AM

Something like this could work for the hose support. You would not need to disassemble the clamp to get the hose out if it is tight enough.

914 mania has encroached upon 911 territory.

Posted by: wonkipop Mar 15 2023, 03:09 PM

yep. i realise now i am going to have to kill myself.


if its any comfort the NARP concept is still alive and well.
filled up the 914 with gas on monday.
nice quiet day, public holiday, city deserted.
was having a real pleasant day.
minding my own business at the gas pump.
then this black macan pulls in and hes got a whole gas station to choose a pump from.
but has to pull up next to me.
gets out.
first thing out of his gob. "ah a nine one four, pity its a volkswagen".
ah. i think. the species is alive and well. c$%ts who drive porsches.
quick as a flash i came back at it.
"yeah - just like yours ....... very nice toe rag you got there mate".

end of conversation.
went off and paid my gas bill.

one thing you can be sure of.
no fool is going to be sitting around in 50 years time sweating a heater hose on a macan. or searching through VW parts catalogues to find the alternative from a toe rag.

A Touareg can tow a 914 from Atlanta to Maryland with only one stop for diesel and BBQ; a macan, cannot.

i didn't realise you could translate auslish!!!

be careful with the toe rag diesel.
my mate just blew his up.
bad dose of diesel fuel he picked up at an obscure country gas station.
its a write off.

basically it hydrauliced the engine on injector overfueling.
V6 version. its either cracked the head or the block.
the dealer couldn't work out which.

i was with him when it happened.
have more details.

if you get bad fuel, stop immediately.
get it towed and cleaned out.

we knew we got the bad fuel and were in the process of trying to get to the dealer.
blew it up before we could get there.

really surprised me.

they are good cars.
i always enjoyed our country trips to job site inspections in it.
real shame.

(if yaa-all interested one day i'll list out all the nicknames aussies rebrand cars with,
kind of ryhming slang. eg ford falcons are known as falc-hoons, because hoons drive em. don't know who rebranded tourags, buts it a good one and its stuck and now in general use. years ago range rovers were rebranded "toorak tractors". holden commodores were commode doors. became dunny doors after a few years. holden sunbirds were sh#tbirds. etc. the list is extensive.

So after 6 pages, WHAT am I buying and WHERE am I buying it from...

Posted by: Sprout Mar 28 2023, 08:06 AM

Here's a pic of the Dorman 96003 hose I installed using the original clamps. It a pretty long hose, so I just cut what I needed to make it fit. I bought it at Advance Auto Parts, I think it was $18.

Posted by: NARP74 Mar 28 2023, 08:11 AM

Well the Dorman/NAPA hose is a good alternative. It is 2.25 in, for those stateside. It is a tighter fit than the 2.5 inch some suppliers sell. NAPA will sell it by the foot so if you are only doing the short side you don't have to buy all of it. If you are doing both sides, you can buy all of it. The long side will need to be supported in the middle by a clamp or something.

Still looking for perfection, sometimes that takes a little longer.

Cheers

Now that my heater hose got sucked in and took out the fan, I am looking at improving what was there.
In contrast to this, my car came with a splitter off of a bay window bus that never fit or worked well.
Does anybody have the 411 splitter for sale or can you give me the part number for #67 above?

Thanks! The price isn't bad, but I don't need the hose. I am going to try some 60mm hose that is closer to the original material.

@http://www.914world.com/bbs2/index.php?showuser=7418 George can I get just the splitter? I just don't need the hose sitting on a shelf unused...

Posted by: scott_in_nh Sep 18 2023, 03:04 PM

I had a WTB ad up to find the hose splitter, that resulted in getting directed to a thingiverse.com 3d printing .stl file of a stockish looking single hose adapter.
https://www.thingiverse.com/thing:2301723 https://www.thingiverse.com/thing:2290245

Using that as a starting point I added 2 60mm ports to it along with holes for the stock spring pins and I added clearance to the sides to look more like the original.
I also made 60mm adapters for the heat exchanger ends so I can used the aluminized stiffer hose that is available.

I'll probably add a support in the middle, but it stands up pretty well by itself.
