Dual Fuel Tanks

The rear fuel tank on my 1995 Ford F150 works only a portion of the time. Is this a problem with the fuel pump or is there a relay problem?

Fuel pump not running on 1995 F150 Ford Fuses good Swapped relay Twin tanks


if neither tank is working check the selector switch it is responsible for energizing both fuel pumps depending on the selection, if you have power to switch and power leaving switch than either its lost on the way to the fuel pump or the pump is bad in this case both?to confirm you must check for power at the pump, easiest is the front tank.

IT WILL RUN OUT OF THE NECK WHEN IT IS FULL.THE FIX IS SIMPLE REPLACE THE FRONT FUEL PUMP. THEY DONT MAKE A CHECK VALVE REPLACEMENT I CHECKED I HAD THE SAME PROBLEM AS YOU.

When I switch from my front fuel tank to my rear tank gas stops


There is no selector valve on a 1995 ford f150 300 engine. The selector switch on the dash sends power to the pump in the selected tank. The pump then sends fuel to the engine. If engine won't run on the selected switch, the pump in that tank needs replaced.

1995 ford f150 fuel pump


Your truck is fuel injected. On the fuel delivery rail in the engine compartment there is a cap you can take off to check for fuel pressure. Hook a mechanical gage to it and check to make sure the fuel pump is working. Also if you have a dash switch to change over to the different tanks check it. Often these switches become bad and the fuel will not flow. The switches are about $ 40.00 dollars. To replace the fuel pumps you must drop the fuel tanks and remove each fuel pump from the tank. The cost for the pumps alone will be about $300.00 to $ 500.00 depending on who you purchase them from. The universals are cheaper, but the Ford pumps are an exact match and you can change them with out any problems.
