According to my friend who I have working on my truck because of a fuel leak, the fuel line assembly that needs to be replaced is F0TZ-9S278-A - He said it is discontinued, but some places may have it.

I can't find it anywhere. It is supposed to be rubber hoses that run from the tank to near the fuel filter.

90 F-150 EFI 4x4 351w short bed

Who can help :\

So far I've tried:
Google (which won't even show a reference to that part number)
www.rockauto.com
www.fastpartsnetwork.com
www.lmctruck.com

If I could find a diagram of a 1990 F-150 EFI fuel system with part numbers listed for the parts, that would be helpful. Where can I find such a thing online?

I haven't ruled out that part number is in error, but he insists that is the number. Without having a shop manual to look up parts in, I am kind of lost.

Thanks for any help.

 

You probably won't be able to find one. But you can get the connectors and make up your only fuel line with high pressure fuel hose. Another option would be to bring the fuel line to a junk yard or the Ford dealer. These lines and the connectors didn't change all that much over the years and finding one that's close will probably get you going.

 

I believe that is exactly what I am going to do. When you say get the connectors, what exactly do you mean? New connectors or somehow adapt the connectors that are on in place right now to the new high pressure fuel hose?

I haven't been under it to look at what the points on the tank and other end of the hose look like, but I was hoping I could just use the fuel hose and fuel injection hose clamps.

Thanks for any info.

 

Which line is it, the one from fuel rail to the fuel filter or fuel filter to the tank? The connectors for the fuel filter and similar fittings can be found at almost any well stocked parts house. The fitting at the fuel rail, although I think they are available, can probably be reused, if you're careful about getting the compression fitting off the fuel line.

 

It is a plastic return line from the union just before the fuel filter to the tank.

I want to crawl under and get pictures but it's raining..

I was in error earlier when I said it was rubber because I misunderstood what my friend was telling me. Once I get the truck towed back to my house, I will probably have a better understanding of what is going on. Right now my only info is what I was being told over the phone because I had to drop it off in a rush yesterday morning hoping I could get it fixed in a day. Now that it's apparent that it would take my friend's shop longer than I want to do the repairs (and they can't get the factory part that's needed), I've decided to just tackle it myself like I do everything else.

 

The return line shouldn't be under that much pressure. I'm sure you can figure out something for it. I had a 92 about 8 years ago, but I don't remember much about the return line.

 

Good deal. Thanks for the tip.

I'm just assuming that the supply line is probably just as brittle and will probably leak soon, so I want to take care of it too while I am under it.

 

I'd leave the good line alone. It's probably OK.

That line is hard plastic, just like the earlier EFIs (but with braided sleeving), and is available at most parts stores in bulk for custom assembly. Instructions are on the packaging for the fittings.
