Engine bay fuel line clamps, what type Options

[1970 Neun vierzehn]

In the refurbishing of the engine bay, I began wondering about the clamps on the fuel lines. The originals, as I recall, were what I call "tension" clamps, sort of "spring loaded" by virue of their shape. I have something similar on my old motorcycle fuel petcock. What they have been replaced with over the years are the typical screwdriver-tightened "hose clamp". The P+A dealer sez the hose clamp is definitely better as they can be "tightened" and don't loose "tension" like the OEM do/did. I don't ever remember the originals getting "weak", as I remember it, they were a nuisance to get off in the first place because they were both so tight, and awkward to access to release the tension they held on the hose.

I'm assuming that the old syle clamps can still be gotten somewhere.

I know what's original here, I'm wondering what's better.

Hate to put pressure on you, but remember it's not original unless you use them. I think they may still be available from the Porsche dealer.

Between you & me I would upgrade to a safety/practical installation with fuel lines, (my opinion).

Tom,

I think what Paul is referring to are the clamps used to mount the fuel lines to the injectors. I say this because your pic is that of the clamps that hold the lines in place.

The original clamps that sealed the rubber/cloth fuel ine to the injectors was a crimp-on type claamp - not adjustable. On my 914, these were replaced with screw compression clamps when Porsche did the fuel line recall ('74?). They still work prefectly today & are very small.

Wish I could show a picture, but it's 28 degrees in my garage (5 degrees outside) & I'm a sissy.

You can get the proper FI fuel line clamps anywhere, cheap. The usual ones are gold plated (nice like oem) but slightly deeper than oem. big deal they don't cut the fuel line like the crappy gasline screw hose clamps. (IMG:style_emoticons/default/alfred.gif)

Next item is what fuel line are you using? I prefer the rubber coated High pressure hose from Porsche or Pelican Parts. You can save your old fuel line sheath too and reinstall it so it look oem but is safer. AA sells the preformed elbows that were part of the recall. don't use the fabic hose that comes on the injectors as it cracks in short order spraying gas all over the place!

Geoff, my 80K mile '76 still has the original hose on the injectors. What do I do and how?
Looks like a bitch to get the injectors out with the extra EGR plumbing in place (first time I have had a 914 with EGR, but it is plugged and not operative).

[Bleyseng]

If its still original seals and the nonrecall fi hose order the injector (inner and outer) seals and the recall supplied special formed elbows from AA. cut the fabric hose off the injector and replace it! Use the special FI hose clamps to clamp it to the injector and fuel rails. This can't be a Concours deduct cuz thats the factory recall method. Hopefully the other fi fuel line has been replaced or do it now like I posted keeping the special sheath and replacing the fuel lines before you have a fire.

[Porsche Rescue]

Thanks. The other lines in the engine compartment have been recently replaced with the fabric covered lines (hope high pressure!). The old lines came in the trunk, very hard rubber hoses. No sheath at all. I have dealer work order from 1977 stating "fuel line recall", N/C. Maybe I don't have the original hose on the injectors but it is old. Better look more closely.

Hey Geoff!

I don't hang around too many parts places, so where can these clamps be gotten? And how are they crimped into place?

Checked PP, PerfProd & AA - no listings for these. Where?!

Here I go again getting confused. What your showing is what I have, from the recall program in 1976?

I thought you mean that there was a source for the "original" pressure clamps - the ones that had no adjustment. They were a metal band with a locking tab, apparently applied with some sort of crimping tool.

Don't really want them, since they were a bitch to remove. The ones you're talking about work perfectly & have for over 30 years on my car. Sorry for my confusion.

AFAIK the recall is still active, and if the car has never had the (HO I think) recall performed, then in theory it could be done free at a Porsche dealer. Worth checking out anyway.

The factory style hose clamps aren't that much more than the worm screw type. One of the few Porsche parts that shouldn't come with a kiss.

[Bleyseng]

Yes, those clamps style fuel line clamps can be sourced but who wants them! The "Factory Recall" replaced the fuel lines and the pictured injector elbows and used the proper Fuel injection hose clamp. Those screw type clamp digs into the hose resulting in leaks, never use those.

For Concour judging, the proper fuel line, elbows and clamps per the recall should be considered as "factory" IMHO.

I agree! That's what my original point was. The "campaign" parts are better & I've never seen a gig for having them. It's like the early 911's with hydropneumatic suspension - even Porsche recommended trashing it and PCA specifically recommended it & denounced points reduction for the refit.

This may be wishful thinking... but how long is a re-call good for ? I'm wondering if my '75 2.0 has had the service done and secondly if I can just stroll into my local Porsche Dealership and have them perform recall number 77V105000, replacing all my fuel hose for free !.

I bought these, very nice, great deal in my opinion.

Speaking of good deals, I just took a chance today and ordered 4 fuel hose elbows, but not the Porsche elbows from Auto Atlanta. ~$13.00 EACH is too rich for me. Instead, I ordered 4 BMW fuel hose elbows, BMW part # 16121176821 from this place: (IMG:style_emoticons/default/idea.gif)

$2.93 each. I believe they should be 7mm I'll let you know how they fit once I receive them.

I found the part number from this website:

The recall is still active for all 914's that haven't had it performed. Your local dealer should be able to tell you if your VIN has/has not been done. If is has been done (probably), they'll probably try to sell you another redo, and that's not a bad thing. If it hasn't, they'll do it. They don't care - get the cost from Porsche.
Find out - it's important

I know I have seen somewhere or heard here, that the recalls for 914s are no longer being honored. Something about 'reasonable time' or 'parts NLA opr something. The dealer network can verify if your vehicle has had the recall though.

The 914 fuel line recall was recall campaign HO.

mine didn't have the HO sticker nor did it have FI when I got it. (IMG:style_emoticons/default/sad.gif)

Jeff, not Geoff, (but thank Geoff also !)

Thanks for the link, I think I'll print out the official recall notice and drop on into the Porsche Dealership and see how many jaws drop on the floor (IMG:style_emoticons/default/blink.gif) when I ask for the HO recall service. I'll keep you posted, should happen sometime next week. (IMG:style_emoticons/default/biggrin.gif)
