My original 6 oil tank came, but now I am in need of some oil lines to connect it to my engine. Where is the best place to get them? PP has Oil Cooler To Tank and Oil Tank To Oil Cooler lines for sale which runs about ~$150. Is that all I need to get it all connected?

On a Factory 6 there is 3 rubber hoses and one steel return pipe.
You have two hoses that go from the bottom (feed) of the tank to the oil cooler on the engine. On the return side it's steel from the engine to the left engine shelf then the rubber hose connects it to the return side of the oil tank. Only other lines on the tank are for the breather and over flow.

PMS sells a new 3 rubber line set for $270.00

So if i purchase that I still need another line? or just need that?

Posted by: mepstein Dec 20 2014, 07:21 AM

also need the steel return.

Posted by: Luke M Dec 20 2014, 07:38 AM

Unless you already have the 914-6 steel return line then yes you will need one.
You have two options here. You can go with a factory 6 line or a PMS modified line.
Only thing with the PMS steel line is you would need a longer rubber return line back to tank. I've seen people run a rubber return line straight from the engine to tank but I don't like that. The steel return line is meant to help with the heat from the headers.

PMS also sells a AN oil line conversion kit.

Also if you have a 911 cooler you need to modify the return pipe on the cooler to 914 style, about $200. The whole stock set-up gets quite expensive.

I debating which way to go, stock or a bit cheaper (hopefully) custom using adapters to AN fittings and hose.

You can see the cooler mod here:

It's not that difficult to make your own AN lines. The adapters and fittings will get expensive though.

I'd use the Patrick Motorsport steel line as it gives you options on adding a future cooler if needed by easily swapping out some small AN hoses. If it's going to be a track car, AN-16 lines would be better, but $$$ and harder to run to the front. AN-12 lines can be made up at home.

I don't have the part number, but there is a 911 flexible line that replaces the hard line (18). It goes all the way from the engine to the oil tank with no other connections. I have one and used it for years.

Posted by: Cfletch Dec 21 2014, 03:04 PM

yeah its for just street use and I wanted to just get everything at once. still not 100%on what I will need.

Posted by: Mark Henry Dec 21 2014, 03:31 PM

Is it this one?
901-107-331-12-M20

http://www.pelicanparts.com/catalog/SuperCat/911E/POR_911E_ENGOIL_pg8.htm#item31

Is this the smaller size line?
I don't know if it would be a big deal on a 3.0- /6.
The line on the 2.0-2.7 is just under .100 smaller than the 3.0-up, but the outlet fitting on the case is the same ID both sizes, so I really don't see the smaller hose being a restriction.

Went looking and answered my own question, the fitting into the OEM and my DWD tank is the smaller cohline. Makes sense, the 914/6 is an earlier car than the 3.0 up cars.

If this is the correct one Clay is talking about, it would be a cheap way to get the /6 up and running, $110 for the cohline or $68 for the "German".
So this hose $68, about $170 for the 2 return lines and the cost of the cooler mod.
Cooler mod from a914guy (Rich Johnson) is listed at $175 plus shipping, so I'll call it $200.

$68+170+200= $438
That's the cheapest "new cohline" solution I've seen so far.

here is another source using cohline hose and stock type fittings

I have the stock part 18 hard line, I'm not going that route now that I bought an external oil cooler.

Let me know if you still want to buy a stock hardline.

Posted by: Mark Henry Dec 22 2014, 11:21 AM

Yes, but you would still need the 914/6 hardline around $400
Also the OE hardline may have issues with some aftermarket engine mounts.

$270+400+200= $870


NOTE both prices I've added up do not include any of the kit needed for a remote cooler, this is just a straight in/out set-up.

Posted by: Mark Henry Dec 30 2014, 01:38 PM

Same as post #15, you still need the 914/6 hardline.

Posted by: johnhora Dec 30 2014, 04:35 PM

Posted by: JmuRiz Dec 30 2014, 07:48 PM

Yep, that's the one, PM me for one at a better price

Posted by: Mark Henry Dec 30 2014, 08:17 PM

I'd use a garden hose before I gave that weasel a dime.

Posted by: JmuRiz Dec 30 2014, 09:05 PM

Ahhh, didn't even notice that.

Posted by: Cfletch Dec 30 2014, 11:24 PM

who is it?

Automobile Atlanta

Do a search and you'll find a lengthy history of debate.

Posted by: Brian_Boss Jan 1 2015, 08:03 PM

That's our kit which requires the stock six hard line. If you don't want to go that route, we can send you a set with a long soft line that replaces the hard line and short soft line for the feed line. PM me or Jonathan for price.

With this setup, you need to carefully route and mount the soft line away from the HE or header.

Posted by: Mark Henry Jan 2 2015, 07:59 AM

Brian is it this hose you are talking about for substituting the hose and hardline?

Posted by: johnhora Jan 2 2015, 02:50 PM

Mark...that is the one....the early SWB 911 68< used this "soft" line...it went up and over the tranny from the engine to the tank...here is a pic of where someone made one....it's #17 in the diagram.....that was used until the #18 version
I've dismantled a few early 911 that had them and various shop made versions and some out of AN fittings and SS hose....never tried to use one on a 914-6...not sure about the length of it to the 914-6 tank....should work just like on 911...keep away from HEs....
