The fuel feed hose sprung a leak today on my way home. This is the 3/8" Saginaw-connector rubber hose that makes a U-shape and connects the steel fuel line on the driver's side fender to the TPI fuel rail.

I realize that the only way to get the hose is to buy it from GM. Therefore, I figured that I could get two female Saginaw connectors with a flared end and run a short piece of high-pressure fuel line between the two connectors with hose clamps. My local auto parts store carries no such adapter. I don't even know if an adapter like that exists but it was worth a shot.

What can I do? Does GM make the adapter that I'm looking for? Part numbers would be WONDERFUL.

This is the type of adapter I'm thinking of using. The threads just have to be Saginaw-style.

 

That's just a standard hose barb. You should be able to get new hoses made anywhere that crimps hydraulic hoses. You can even make your own with reusable pressure hose fittings. These are the parts you would need:



All you need to know is the thread size and pitch. There are no proprietary threads any more, so the fittings or adapters are available somewhere in the aftermarket. Stop looking at auto parts suppliers and start looking at industrial fluid power suppliers and you'll find everything you need. If you get a measurement of the threads, I should be able to give you a part number for the fittings.

 

Thanks, Vader. I read somewhere that the fuel line connectors are Saginaw-style 14mm x 1.5mm for the return line (5/16" line), and Saginaw-style 16mm x 1.5mm for the feed line (3/8" line). AN Plumbing makes a Saginaw-to-AN adapter but I think I'd need another fitting, an AN hose barb, to make it work. It'd be nice to cover all bases with just one adapter.

Is my approach correct? Would a typical hose barb be able to support a high-pressure TPI fuel feed line? Or is that when I'd get custom hoses crimped?

 

Its always fun digging old dirt!!!

Anyway, I just burst my feed line as well. GM has discontinued the part and the female fittings needed to make a new hose are not available, at leat by my search here locally. Earls appears to have adapters but I havent held them in hand, they convert to -6 AN. I picked a line from the local yard but plan to replace it ASAP, I only need it to drive the car up on a trailer and get it home from my buddys house.

If anyone else has info to share now would be a great time before I spend 75-100$ on Earls fittings and stainless line.

 

I went to the junkyard shortly after this happened and bought every fuel line hose from every third-generation F-body there was. I just put a little leather cleaner on the hose to keep the oils in to prevent it from cracking.

I'd just make sure that the hoses are in good shape; you'll probably be OK. I also tried making a hose from the old adapters... I cut off the crimp and put two hose clamps on each end. That held up, but I wanted it to be less noticeable -- which is why I went with the junkyard parts.

 

I just bought the pressure fuel line from GM (I'm in canada)
and they ordering me the return flex line as well

was replacing the O2 sensor... dislodged it...
sprung a leak...

so GM has them... it cost me $50 including the O rings.

Post the part numbers.

 

I don't have the part # for the return yet....

the pressure line I got is for engine code F. (305)
it's like a foot too long, but the right part #
I'll get the part # for the return line this week

pressure line flex hose: 1011 3094

 

I replaced my two fuel presure hoses for CH$ 8.000 = US$ 11.30 ( US$ 5.15 each). They were "home made" in a shop.

You can try in a "Dayco" dealer (fuel hoses) or "Dixon" dealer (adapters and fittings). If they have a machine shop, they can made the job for less (they can use the older adapters with new hoses).

The return line rubber fuel hose from engine to fuel rail part # is

10068767

hope this all helps.

 

Vader,

That scan is the fitting from the fuel rail side? I need the part number for the rubber hose fittings that attach to the steel fuel lines on drivers side fenderwell. My local hyd line shop says they're not available aftermarket. Here's a picture of one of them.

 

TTT for Vadar

Do you have information for the part number of the fuel connector I posted a picture of?

 

You can use the same fuel connectors. They are re-usable. The only that you needs is a piece of rubber fuel hoses (3/8 + 5/16). In a little machine shop, they can cut the "sealed type" clamp and replace it for a new one. In the last picture you have the solution in your hand.

(The yellow adapter shown in your first picture don't work. It produces leaks).

 

I'm unsure if you're replying to me or to the orginal poster.

I know they are re-useable, I want to find out where I can get then new by themselfs with no hose on them.

 

Oh, yes, I was confused in my last reply.

Only note that the "Home Depot-style" connectors are not good.
