The gas gauge is stuck past full on my front tank but when i switch to the rear tank the gas gauge works just fine how do i fix it because my rear tank leaks so i cant use it and i dont know how much gas i have in my truck and i have ran out a couple of times now
Replace front fuel pump because gauge is made into fuel pump and not serviceable. Or poor boy way of getting by would be fill front tank with gas reset mileage drive normal for a day. refill again with gas note gallons used and mileage driven for average miles per gallon. front tank should be around 17 gallons multiply by mile per gallon you figured

The switch that you use to change tanks is probably faulty - the switch supplies power for the sending unit in the tank, and to the transfer switch for the gas lines - use a meter to check it

yea fords with two tanks are known for getting stuck if you dont switch the tank constantly. you have to get to the valve that switches the two tanks, and free it up. it definitley isnt anything but the valve.
SOURCE: Fuel leaks from rear tank to front.
The leaking from one tank to another was covered by a recall from Ford. Not sure if they still foot the bill for installation of the required check valves. These are still available from the dealership. The rear one is the hardest to install. The check valve can be installed without pulling the rear tank. As for your front sender I would clean all of the connections to the sender and make sure it has a decent ground. If it still only reads at the 1/4 tank level you will have to replace the sender to rectify the problem.

i think u have a bad fuel pump, switching unit does nothing but not allow fuel to be pumped from tank to tank, for example if useing rear tank lets feul flow to engine not iti nto frt tank,when it goes bad you will see gas flowing out of frt tank because its pumping into tank from rear tank,good luck.check fuel preasure w rear tank is on.
Testimonial: "Thanks for the response. I checked w/the Ford dealr parts guy who said each tank pumps directly 2 engine. Not sure how it works on other trucks tho."

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.
