I have a 1992 Ford F-150 with a 4.9L V6. It also has the dual tanks. I have seen so many conflicting statements about the components of the fuel system on this truck since I am experiencing a problem where when I use the front fuel tank (rear fuel pump is not working), fuel is running back into the rear tank and causing it to overflow. This truck has a fuel pump in each tank and another along the rail if I read everything correctly. However, what I'm unsure of is whether or not this truck has a fuel tank selector valve, or just the switch on the dash and the 3 pumps. Also, whether or not this issue would be solved by replacing the rear pump, which I believe has the check valves inside them.
have the same problem?
