    The fuel crossover valve

  • gstodt Feb 26, 2009

    1987 Ford F150 (straight 6 cylinder) - Fuel being pumped from rear tank to front tank, then overflowing out the filler cap. The fuel selector switch, when switched to the forward tank does not work (probably a fuel pump problem). I end up having to manually transfer gas from the forward tank to the rear tank.

    I cant get the fuel out of the front tank. I need to know where the relay switch is located under the truck. I have a 1994 Ford F150.

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.

What controls the temperature gauge on a 1990 ford f150 5.0 engine and where is it located


The temp gauge on the dash displays the information transmitted by the coolant temperature sensor. This sensor is located - on the engine - by the water neck. The water neck is where the top radiator hose comes across and connects to the radiator. This sensor can look like the one here:

Dont no were horn is located to replace


Check the front part of the engine compartment by the radiator. It's a black, curved object that is attached to the front cross wall along with the radiator. At least that's where it is in the 1989 F150. Hope this helps. Good luck!

1990 f150 transmission up shift to early


your modulator valve is unhooked, or bad. The modulator valve is what tells the transmission when to shift and what gear to shift to. It is located on either side of the transmission depending on the model, Im not sure which side your perticular model be on but it looks like a spark advance. I hope that helps you out.
