On Amazon F1uz9b263b Reservoir Assembly - Fuel Selector Valve Oem Ford


Ebay - F1UZ-9B263-B Fuel Tank Reservoir Switching Valve Fits F150/F250/F350 FREE SHIP! $125.00


first understand what you have to work with, two tanks, two pumps, two controlled check valves, a return fuel line, and dash switch. the simplest way would be just drill and tap fittings low side of tanks and install a jump line.for'll always be running one pump or the other from the dash switch. you also retain an extra pump if one stops working


There is also a lift pump on the frame rail on this model.
