Dual tanks on 1990 Ford F150

I have a 1990 Ford F150 XLT with a 351 and E40D auto. It has dual fuel tanks and the rear tank has started leaking. I am wondering if it is possible to just remove the rear tank and block off the fuel lines, or would it cause any problems?

It should not cause no problems but instead of removing the tank leave it in the truck take out all the fuel in the tank and jus discontinue use of it. This will save you alot of time and trouble and i also suggest that if anyone besides you drives this vehicle then i would put a locking gas cap on it so it cant be accessed at anytime except by you.

I have a 1994 Ford F150 XLT with duel fuel tanks! I have a full tank in the front tank, but when hit the switch for that tank, the truck goes dead! What is the cause of this?


common on older high mileage fors to either have the switch go out or the intank pump go bad, you cang ground terminal 6 on the underhood diag plug with key on engine off and switch from front to rear or vice versa and listen for fuel pumps to be running, likely one is not

Replace the fuel pump relay. And if your truck has dual tanks there's three fuel pumps, one in each tank and another secondary fuel pump.

1990 ford f150 cross over valve location


Please Help ME by Remembering to RATE ME Thank you Vrey Much !!!

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.
SYSTEM: FUEL TANK, AUXILIARY.
VANS AND LIGHT TRUCKS WITH DUAL FUEL TANKS PRODUCED IN THE FOLLOWING PERIODS: F150, F250, AND F350 LIGHT TRUCKS BUILT BETWEEN FEBRUARY 28, 1989 AND JULY, 1989; ECONOLINE BUILT BETWEEN FEBRUARY 28, 1989 AND FEBRUARY 11, 1991.
NOTE: FORD HAS AGREED TO RECALL THESE VEHICLES BUT PARTS ARE NOT YET AVAILABLE.PARTS WILL BE AVAILABLE IN DECEMBER 1991. YOU WILL RECEIVE A LETTER FROM FORD ADVISING YOU WHEN TO SCHEDULE AN APPOINTMENT WITH YOUR DEALER TO HAVE THE RECALL WORK PERFORMED. IN THE MEAN TIME, YOU CAN TAKE THE FOLLOWING PRECAUTIONS:FILL EACH TANK TO ONLY 1/3 FULL. IF YOUR VEHICLE LEAKS FUEL OR IF YOU SMELL FUEL, STOP USING THE VEHICLE AND CALL FORD AT (313) 446-4654 AND ADVISE THEM OF YOUR PROBLEM. REFER TO FORD SAFETY RECALL NUMBER 91S39. AN OPERATOR WILL TAKE YOUR NAME AND TELEPHONE NUMBER. A FORD REPRESENTATIVE WILL CALL YOU BACK
