Where is fuel pump on 1991 f-150?

Your fuel pump should be in-tank for a 91 F150. To access it, you will likely need to drop the tank.

You should verify, however, that there are no ignition problems before considering the fuel pump and always remember to replace the fuel filter with the pump if it does turn out to be the pump.

Have the same truck and had the exact same problem. Mine spilled out the front tank. Ford did a recall on this problem. They put valves on the lines outside the tanks. Mine had already been done so that was not the problem. The pumps have valves inside for the return lines. I replaced the rear pump, didn't fix it. Replaced the front pump and Voila ... it was fixed. Bad valve in the front pump return line.
