SOURCE: fuel tanks not switching

It likely has a bad lift pump in the front tank. If this is a gas truck it has 3 fuel pumps, one in each tank (Low pressure, lift pumps) and one on the frame rail. Check for power and ground at the front tank for the lift pump.

SOURCE: 88 Ford F250 rear gas tank will not work

Sounds like the rear fuel pump in the tank is not working and the float or sender is bad also. check to see if the rear pump is working should make a humming noise.

SOURCE: My 1997 F250 has duel gas tanks. After a few days

I would start by checking you switch for the tanks to make sure it is working right and if the front tanks fuel pump does not work after you check the switch I would get a 12 volt electrical test light and see if your getting power to the front fuel pump if your getting power to it I would say you have a bad pump . But some times the pump will run but the diaphragm gets weak in them.

SOURCE: 1996 ford f250 truck 4x4 5 speed 460 will not start

Running tank one empty could have picked up **** from the bottom of the tank and clogged the in line filter that feeds the engine. It should be located under the truck on the left inner frame rail around the back of the cab area. Replace it don't try to clean it out it will just clog again. They are not that expensive from the locale parts house. DHR... EX Ford Line Mech

1996 f250 fuel issue


check for a resistance in the circuit to the pump
from your description when you have high rpms you will have max charge from the alternator which would increase the voltage available to that pump
bad connections , bad ground (earth)
tyr using a multimeter set on voltage to see the operating voltage available and if it increases with the rpms

The fuel pump relay and the oil pressure switch as well. The oil pressure switch runs power to the fuel pump when you first start it
When the oil pressure reaches operating range the relay takes over
They are both inexpensive so replace both of these parts to be safe and kill two birds with one stone. If one goes out the other will soon enough

Front fuel tank will not work


You have duel tanks with a fuel pump in each tank. You also have a fuel pump on the frame rail after the "tank selector". This device only holds a fuel filter that protects the main fuel pump. When you select front or rear tank on the dash, you are selecting which in tank fuel pump will operate. You can check the in tank fuel pump by listening for it to "humm" when the key is turned on..The in tank pumps only feed the main pump and cannot run the engine on their own. Hope this helps
