I have a 95 F 150 with short bed and duel tanks. here are my problems -0 gront tank reads pegged past full, all wiring looks good. when I switch to rear tank, guage reads good nut drops VERY fast, I figured out that the rear tank; besides running truck is pumping gas into front tank. Is theere anything I can do about these problems?

 

also - where is the transfer valve?

 

It does not have a fuel transfer valve.
You have bad valve(s) in the fuel delivery module in the front tank.
You also have an open in the circuit of the front fuel gauge sender or sender itself.

 

where is fuel delivery module, and how do I replace it?

 

I think he is trying to say ( open ) broken wire or break in the circuit inside the module.

 

It is inside the fuel tank, you have to pull off the bed and remove and replace it from the top of the fuel tank, the easiest way.
You can also drop the tank but that is the hard way to do it.

It can be but it can also be somewhere from the tank to the switch on the dash or the dash switch its self. When you have open in the circuit going to the fuel gauge on a 95 the gauge will peg.

I dont own a 94 on up but yall just answered a question for my father....I am calling him right now....he been sucking gas out his front tank so it doesnt over fill for 2 years now

 

Well I was working on the dash of my 92 and inadverntly ( I hope I spelled that right ) left the selector switch disconnected and the truck wont even start. Just winds and winds.

 

This only applies to a 1990 and newer f series gas truck or 1991 and newer e series van. I hope that is what he has.

 

Uh huh, and on those that have single tanks like mine, there is this nifty little plug that replaces the switch, which is also the blank in the dash panel. I didn't think it was necessary, but oh is it ever. That plug is actually to jumper the same wiring harness as the dual tank system to connect the only pump and gauge that a single bladder truck has. I found this out the hard way. Did you happen to notice that your fuel gauge pegs out too?
