I've been having some issues with fuel delivery on the '89 with 460.
The mechanical switching valve and the frame rail high pressure pump were replaced a couple of years ago. Lately, the truck stumbles when accelerating, and it dies when I switch from the front to the rear tank. Since the fuel gauge does not read on the front tank, I ordered the whole setup for the front tank, sending unit and pump, which I will replace. After that I will order an in-tank pump for the rear tank.
The fuel filter on the frame rail and the relay for both the fuel pump and the EEC have just been replaced with no change.
Am I missing anything?
