Question about 1990 Ford F150
Fuel pump locations
Dependant on your model specifics, either two or one tank assembly, the tanks themselves will have a sending unit inside. You can replace just the pumps for less but you MUST exercise care when removing reinstalling and cleaning. The orig sending unit can be brittle. The plastic parts to specify. If just trying to get a truck running, start with the rear tank, and if you cannot save the tank straps you can ratchet strap the tank to the frame to make it mobile. DONT DROP THE TANK OR LET IT HANG. While under the truck lean the back side of the tank off first and it will give access to the connections you need to remove to drop the tank

This vehicle does not use an external fuel tank switching valve. A supply check valve in the fuel pump assembly opens when the outlet pressure from the energized fuel pump exceeds the opposing check valve spring force.
R E C A L L 1991
THE DUAL FUEL TANK SELECTOR VALVE MAY MALFUNCTION AND CAUSE AN OVERFILL CONDITION IN ONE OF THE FUEL TANKS, RESULTING IN AN OVERFLOW OF FUEL PAST THE FILLER CAP.
THE OVERFLOW OF FUEL PAST THE FILLER CAP CAUSES A FUEL LEAKAGE, WHICH CAN RESULT IN A FIRE WHEN EXPOSED TO A SOURCE OF IGNITION.
REPLACE THE DUAL FUEL TANK SELECTOR VALVE.

Engine Compartment fuse panel ( driver's side fender ) relay 301. Layout with numbers should be on the lid ( numbers only, not the functions ).
If you did not get an owners manual with your truck ( purchased used / lost ), you can download one from Ford in PDF format:
Makes it real quick to search for keywords.
