I have a Ford F150 1992 that is leaking from the fuel system. Ford Consumer Hotline reports that a recall was performed, but has no record of a date, only a dealership. Dealership has no record of performing recall. In any event, whether it was performed or not, the check valve has gone out again. To me this is a serious safety issue. NHTSA has an open investigation in regards to this recall. Has anyone been in this same situation? Ford said to contact them if it catches on fire!
15 years is pretty much past the life expectancy for any fuel system. Time for a fuel line replacement...don't expect it to be done under warranty for a teenage truck.
Where is this "leak"? Are you sure it's not over filling the front tank? If you use the front tank first, then go to the rear, does the leak stop?
I had an intermittent problem on my 91 F150; when the front tank was full and I used the rear tank first, it returned the fuel to the front tank, thus over filling it.

Hi Fred, Your fuel injection pressure regulator maintains the correct pressure for your fuel injectors but by design allows fuel to constantly return to your fuel tank. This keeps the fuel from heating up and causing problems.
The return line routes the fuel from your fuel pressure regulator back to the tank. When you switch tanks, your drawing from the other tank but your return line is still stuck on the original tank. Consequently, you are transferring fuel from one tank to the other.

Google: "ford F150 fuel overflow" or "ford fuel transfer", plenty of people have had this problem...
With all due respect Steve, how can you be sure of this with the limited info the OP has provided. He has never stated exactly how this leak manifests itself.
My clue was the "only has problem when both tanks are full"?
