Question about 1985 Ford F 250

1 Answer

Fuel Tanks reversed , Gauge not reading?

My 1985 F-250 6.9 L. Diesel Super-Cab Fuel Tank Selector Switch isnt switching to other tank. with both tanks "FULL." I ran it on "REAR" tank till it was low on the gauge. I switched the dash switch to "FRONT" tank. No change on the gauge. I tapped on both tanks to check for fuel. For some reason the "FRONT TANK" was EMPTY! But, the "REAR-TANK' has plenty of fuel?
I have checked the fuse, The gauge is working and still reads an 1/8 of a tank when the Ignition is turned "ON." It also drops to "empty" when the Ignition is "OFF." Can somebody tell me what is going on?

The Ford trucks were recalled for the tank switch replacement. Somehow the switches would pump fuel from one tank to the other. This would cause the one tank to overflow and or result in a fire from hot exhaust temps coming into contact with the fuel. Check the dash tank switch. It is probably bad.

I have Nissan patrol super safari mod.2005, problem with fuel gauge main tank showing maximum spare tank minimum please help


if you have 2 fuel gauges working of a tank switch there may be some resistance in the circuit of the second circuit that increases the reading of the gauge. Personally I have the tanks balanced out with a levelling hose between them the the gauge reads the capacity left in the tanks IE full-- both tanks-- full, 1/2 both tanks 1/2 With the way you have it set up then if one gauge is faulty and shows full when it is empty you can find yourself in a spot of bother when you need the other tank

the fuel gauge should not be replace as it should be only one for both tanks when you switch tank selector the wiring also switches so you get reading from the tank you are using .now to replace the fuel pump you have to drop the fuel tank, some people say its easier to remove the bed but i disagree. hope this helps you

My f350 1997 will not run on the rear tank . how do i go about finding what the problem is?


well, first, to find out if its the in tank fuel pump or the tank selector valve, the cheapest and probable easiest thing to do is find the selector valve under the truck and switch the incoming fuel lines. front tank to rear tank inlet, and vice versa. If the truck still doesnt run, you either have an electrical delivery problem to the in tank fuel pump or a bad fuel pump. If after switching the lines, it does run, then you need a new selector valve

Fuel gauge wont work on 7.3 diesel. is there a way to test it ?


is it dual tanks? it could be in the switch if it is, most of the time it is bad grounds to the tank unit. grounding the wire from the sending unit to the gauge should make it move, one way or the other

1992 f 159 dual tanks fuel guage not working


You will need to remove the wire for the sending unit on the tank and ground it to the frame with your selector switched to the tank you are working on and the key on. If gauge comes up to full then the sending unit is bad and gauge is good. Repeat process on other tank. The fuel tank switching valve on the frame also switches the wiring signal from either tank for the gauge. If no change with first test you will want to check the valve.

When I switch from my front fuel tank to my rear tank gas stops


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.

as long as the fuel pump is running you must have a restriction in a fuel line.
