Question about 1990 Ford F250

1 Answer

I have a 90 F250 4x4 with dual gas tanks. The rear tank needed a new pump so had it replaced. Now, I got a new problem, the back tank pumped fuel into the front tank to a point gas flowed out the filler port. Anyone got any ideas what is happening?

The diverter valve that shuts the flow off to fuel tank, and transferes over to other tank is bad. here is a picture of it--1990 f250 valve. I have a 90 F250 - selector_small.jpg

Check tanks for balance tube between tanks If the air pressure is not allowed to equalise between tanks then the vacuum formed will not allow fuel to flow to the pump. Breathers on both tanks are a start.

I have a 2000 gmc 3500hd,the fuel gauge stopped at half way and i run out of fuel. the rear tank is not sending fuel to the front tank?


David Johnson is wrong about that. The Chevy HD dual tank has two sending units, one in each tank , one fuel pump, a fuel pump relay switch and a equalizing pump. If the truck stalls out at 1/2 tank, it is the equalizing pump. That pump, pumps fuel from the rear tank to the front. If the pump is out, the front tank empties, the truck shuts down, the guage reads half tank because the back tank is still full, but the equalizing pump won't pump the rear fuel tank load to the front. Hence the problem you listed above, not a sending unit.

Can I replace a fuel pump in a 2002 toyota sienna? do I need to take it to an expert


Wade, you can do it. just buy a manual for your vehicle. it will give you detailed instructions. Plus you can use it later for other problems that arise. you will have to drop the fuel tank. A novice can do it in about4 or 5 hours on the ground.

It could be the pump but you need to verify if you can hear the pump running after it stalls and you turn the key back on to try and start it. If you don't hear it it isn't running.
The pump is inside the tank but it dosen't come inside, you need to put it in there. That requires removing the tank. On a 90, there is a filter mounted on the chassis near the left rear tire. I'd replace that first as if you replace the pump, that should be replaced as well and if it's plugged up it may in fact be the only problem.

Make sure you have the check valves in place on the lines at the sending units on the tanks. If the switching valve on the frame rail goes bad it can push fuel back up the return to the opposite tank than you are pulling from causing fuel to push up and out the inlet. If these were not removed and replaced on the new sending units they will have to be purchased from the dealer.

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.

You will have to remove your back seat to gain access to fuel pump. Fuel tank is located in trunk. No need to take fuel tank down.

F-250 FUEL PROBLEM


Hi, My brothers 250 had the same problem and is now fixed.The fuel pump in each tank has a check valve that allows the fuel to run in one direction only. When this valve fails to close fuel runs into that tank when the other pump is running. We replaced the pump and all is well. Dan
