If your front tank was much less than 1/2 full you may have a bad pump in the front tank. each tank has a low pressure pump that feeds the high pressure pump on the frame rail. If the pump in the tank is bad, the high pressure pump will draw gas from the tank (especially the front tank) until the tank get below 1/2 full then it loses its prime and the engine will stall. Try disconnecting the electrical connection at the high pressure pump on the rail and then cycle the key on and off and see if you can detect the tank pump running or not.

I would look at the fuel filter and follow the fuel line to see if there is an inline filter. then I would check to see that any rubber fuel are in good condition and are not collapsed inside or plugged. I ould also check the gas in the side tank if it hasn't been used for some time.

My 91 f250 gas switch when swiched from fr to back shows gas in rear(and gas is in tank 3/4 full ) but moter dies sounds like fuel pump is operating but will not run


There are several things that I would check, Richard. The most obvious is a fuel line leak from the rear tank. Another possibility is a kinked neoprene hose near the tank's fuel pump. It the rear tank has not been used for a while the tank may have some water in it. Try a bottle or two of water remover (isopropyl alcohol). If none of those things are found, then you should get a fuel pump pressure test.

The gas gauge for the front tank on my 1992 F150 is stuck past full


replace front fuel pump because gauge is made into fuel pump and not serviceable. Or poor boy way of getting by would be fill front tank with gas reset mileage drive normal for a day. refill again with gas note gallons used and mileage driven for average miles per gallon. front tank should be around 17 gallons multiply by mile per gallon you figured

I have a 1986 ford f250 6.9 disiel and I am having starting problem and only when it sits for 6 hours or longer. I just bought it like a week ago and the guy had it for one year. He said he just replaced...


with the older diesels if you run the tank dry you could airlock the injector rail. to bleed them you must crack the lines up top while the pump is running. engine off. due to high pressure.

Sounds like the rear fuel pump in the tank is not working and the float or sender is bad also. check to see if the rear pump is working should make a humming noise.
