I have a 93 F-150 2WD with the 302. I have beed researching the ford fuel tank transfer problem. Because I am experiencing the same thing with my truck. rear tank transfering to the front tank. As far as I can tell I do not have a Fuel selector valve. My question is as follows:

1) Does anybody a a fuel system diagram they can send me that shows the detailed parts list.

2) Why isn't this problem being adressed by a recall? There is a recall on some trucks but aperently mine is not included. Why not ? its the same problem!

3) As far as I can tell it is the discharge check valve on the fuel pump that is causing the problem. Allowng fuel from the front tank to backflow through to the front tank. Dealer says to replace the fuel pump. BAD DESIGN!!! The fuel pump costs ~$200. +labor!

4) How does the return from the injectors find it's way back to the right tank. Is that the real problem? is that also part of the fuel pump?

5) Should I start a Ford Fuel transfer website.?

Thanks in advance for the info.

 

Been there, done that, got the T-shirt. There was a half-a** recall for this but it doesn't fix the problem for very long, and most dealers will simply look under your truck and tell you it's already been done. Root of the problem is poor fuel system design. Be that as it may, you need to change the fuel pump in the front tank, it's check valve is bad and is built in to the pump. It's not hard to do once you gain access to the tank...either by dropping the tank down (a real headache) or by scooting your bed back. I have done both and the latter is easier. Remove your bed bolts/nuts, loosen the fuel tank filler hoses on the bed side (not tank side), unplug your rear taillight wires and tape them to the bumper or frame. Make sure your tank is empty and depressurize the fuel system by pushing down the fuel safety shutoff switch and cranking it a few times. Now remove the tailgate and get a buddy to help you lift the bed and move it back about 2 feet. You can now get the the front tank and fuel pump with ease. Shop around for the pump, you can get them for less than $200, but that ain't bad if it lives for 5 to 10 years. This is the real solution I know of. You will need some small wrenches to remove the pump from its bracket once its out of the tank.

Sorry, I don't have it, but I have the same problem.

I wish mine was included. Back to front for me also.

I have to agree: bad design! There are so many trucks out there with exactly the same problem.

Can't answer that, sotrry.

You'd get my story for it!

Thanks for the feedback . About the Website...I really think that the problem should be adressed by Ford. Granted my truck does have 126,000 miles on it ...But if the component is prone to failure the replacement should be easy not "Engineered" to be difficlt. Well thats enough ranting for now . I feel better already...On a side note : My mechanic suggested installing the Ford recall kit that installs a new fuel regulator and some inline check valves I have a part number somewhere if someone is interested. Just wondering if anyone has tried that, instead of replacing the fuel pump.
