1997 Ford F250 gas with dual tanks

Asked by Apr 27, 2011 at 04:44 PM about the 1997 Ford F-250 2 Dr XL Extended Cab SB HD

Question type: Maintenance & Repair

I have a 97 F250 big block gas engine with two tanks. It will not run off the front tank but when you move the switch on the dash the gauge works fine. Also, it seems like fuel is being pushed from the rear tank to the front tank as it runs out the filler cap and is under pressure. I cannot hear the front fuel pump run even when you cycle the key. Is there a switching valve in the system or is the problem with the fuel pump assembly?
