928drvr86.5

I had this U-shaped fuel line on order, the one that passes under the MAF and joins the left and right rails. I was just informed that this part is no longer available, how now brown cow? I cannot just go down to Joe's Custom Hose and have one made can I?

All of the rubber fuel lines in the engine bay but this one were replaced this summer before the Denver OCIC, it's 21 years old! 86.5 MY.

This came up again recently.

Thanks, What i take from that thread is that you can have one built pretty easily.

I had a Trans cooler return line start leaking awhile back and tried to see if i could have one made when i found a new one would cost $180. Every Hyd/hose specialty shop i took the hose to marveled at the fittings on that line and told me they have never seen anything like it.

I don't know how easily it can be done, but I will be faced with the same issue in the next month or so. I guess it may depend on what services are available in your locale.

It's not high pressure enough that you can't cut out the old line & crimps (the steel fittings are barbed underneath), & use new 5/16" EFI fuel line with EFI hose clamps (I like using double on each end). Worked before.

Mark,
Dumb question I know - where do I get EFI hose and hose clamps?
Thanks,
Roger

Roger,
Kragen Auto Parts stocks it ( at least here in SoCal ) and sells by the inch!

Neil,
Thanks - I will try NAPA here in TX.
Sounds an easy way to solve a major problem.

Yes, NAPA should be fine. Ensure its printed on the hose: EFI Fuel line or Electronic Fuel Injection: otherwise you just get low-pressure fuel hose: will burst in time. About $11 in parts I've found.

i would suggest against just high pressure fuel hose and hose clamps like they have in the auto part stores. "High pressure" by there verbage is for fuel injected and rated at i think 70psi, where as reglar hose is maybe 50psi for a carburated car which runs at 8-12 psi. I would replace that hose at a hose shop, they are pretty cheap, the reason you go there is that they have the tools to remove and replace the fittings, dont substitute one of those for a crap little screw together hose clamp! You probably wont have an issue with the hose bursting, but you may have an issue with the fitting coming loose and then all you need is a tiny spray of gasoline and your car goes up in flames, like more then a few 928's have!

Please dont replace fuel hoses like that like the previously well recomended shop in the Bay area does, that shocked me when i saw that on the engine i bought from them. Needless to saw it was replaced immediately.

RyanPerrella

i think you could get hose replaced for less then $50 for each peice, and lets think there are just 3 parts with the flexible line. You can probably get them all replaced for less than $100 as the length of the hose is only maybe 6" on each part but you just need the tools to properly crimp them. Just get them replaced professionally please!

ROG100

Well from my many years of selling similar fuel hoses with crimped ferrules I would say that there is not a lot of difference. A ferrule or a clamp. Both compress the hose against the fitting. With care the crimp will be just as good.
It is not the fitting that is failing but the hose itself.
Using a more modern type hose will cerainly help.
If I can get them remade using a crimped ferrule I will but if I can't I have an alternative.
Judjing by my fuel pressure guage the pressure does not get above 50/60 psi which is a very low pressure indeed.
6000psi aircraft sytem and I would be really concerned with using clamps.
Just my 5 cents.

RyanPerrella

yes Roger you certianly have a point, you could do it 1000 times and 999 times you wouldnt have a leak, pretty good odds but when i mentioned that i thought they would fail, i wasnt thinking so much the first time you do it and install, rather a yea down the road when you replace injectors, or repaint your intake manifold or something else after youve forgotten about it or sold the car to someone that dosent know. Yes it will work but for a hose that can destroy a car and possibly you i would try afwul hard to have them professionally replaced before doing something with screw to tighten clamps.

I think for the most part the only thing that should be recomended is that it be replaced by a professional supplier. There are some on Rennlist that dont have experience with this type of thing and may not know much about cars in general. As for suggestion i think it should only be suggested to replace properly, but someone with their own experience and wisdom, if they think there is another alternative they obviously can decide to use that method.

I did exactly the same thing. EFI lines with EFI clamps. Don't ever use regular(worm gear) style clamps on FI. They can easily fail under pressure.

RyanPerrella

yeah worm gear thats what they are called
