Fuel Transfer from Rear tank to front tank?
I have a 1997 Ford F-350 with the 7.5 liter...
When I run it on the rear fuel cell it will transfer the fuel to the front fuel cell while I am driving... If the front fuel cell is full when I run it on the rear cell it will actually over fill the front tank and the fuel will run onto the ground while the truck is running. Help, anyone? Red 5 |
you have a bad fuel pump which has a built in check valve that has gone bad. I had the same problem on my 96 F350 CCLB 4x4. Change both pumps and be good. BTW the tank that is filling is the tank with the bad check valve.

in 97 the truck does not have a selector valve, instead each tank has a fuel module unit (FMU) that contains the pump, sending unit and backflow valves and they are simply energized individually to pump fuel and open the return valve. the FMU is for the most part not serviceable though I am sure that there are those who could. :-drink
