I had same trouble with my 05 F150. A wiring harness underneath (below drivers feet) was coroded). On mine it was in a plastic cover on outside of frame. About 4 wires total. Dealer bypassed the one for fuel.

1988 F250 4x4 Rear gas tank leaks when full. Looking for photos or diagram of installation of rear tank parts and tank

Changed both tanks in my 90 F-250 4x4 last year. Get a repair manual Haynes or Chilton, for $20 or so online or at parts store. I have both which have good diagrams and tips for gas tank replacement and everything else. Some big parts store chains have some of this info online.
Gas is to $$$$$ to leak any, besides, you don't want to blow up when someone throws a cigarette under your truck.. good luck, countrycurt0
