SOURCE: dual tank no fuel/1989 F250

The metal fuel line on top of my 89 Ranger fuel tank rusted out. What a pain. For all the trouble of dropping the tank and wrestling with the fuel assembly, definately put in new stuff, don't try to fix anything with jb weld like I did. It's a shame the body bolts are such a bear, or I'd say to try to remove the bed for a good look-see. After all was said and done, I cut a trouble door in my bed so I could replace the filler hose if I ever get one. Just don't do any cutting while the fuel tank is there, even with a saw or grinder, they all spark!

all you need to do is listen to hear the tank switching valve is working. It will make a soft noise under the rear cab section with the key on with the engine off. zif you do hear it sounding the switch your tank unit for that one tank you try to switch to is a fault. Sorry no illustrated diagrams are on hand, just knowledge

Yes I have a 96 Ford 150XL with Dual tank,it won't start ,the dual tank selector valve needs to be changed ,where is it?


I have a 90 f250 xlt, follow your main gas line to where it splits into a "Y" shape, there should be wires controlling the valve, that's where I found mine.

1997 F250 with dual fuel tanks. Fuel from the rear tank siphons into the front tank. When I try using the front tank the engine cuts out under load. Also truck wont start using the front tank


If fuel injected. the tank selector valve switches both the suction line from the tank and the return line back to the tank. It sounds like you have a stuck or bad tank selector valve if the return is not being ported back to the rear tank.

I have a 1995 f25,the back fuel tank doesnt work and the front tank drains intp the rear..what should i do


the fuel tank switch valve is bad. It is pumping fuel to the other tank instead of the engine. There was a recall for some models in 1989-91. I think you need a selector valve, just my guess.

here is some of what it says:

Your truck is equipped with a dual fuel tank selector valve which is designed to direct fuel to the engine from one fuel tank and returns unused fuel to the same tank. It is possible that the dual fuel tank selector valve on your truck could leak internally and as a result return a portion of the unused fuel to the tank other than from which it was drawn. Should this occur when the other tank is at full capacity, fuel could flow out the filler pipe of the tank past the cap. Fuel spillage in the presence of an ignition source, presents the potential for a vehicle fire.

1987 f-150 dual tanks fuel problem


You are right. There are three pumps. It sounds like the transfer pump in the front tank is bad. The in tank pumps just supply the high pressure pump to keep it primed. You need the front pump.

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.

1985 CHEVY TRUCK NO FUEL FROM EITHER TANK


sounds like the fuel tank selector valve is bad, it should be located between the fuel tanks.could just be a wire off so you might want to give it a close check before buying one. and as long as you are under the vehicle you might want to check that it is getting electrical power to the valve/switch.
