    Does anyone have a schematic of a '96 fuel gauge wiring with dual tanks? Both fuel level senders have quit a gauge pegs out at over full. I am suspecting the valve is leaving the circuit open but I don't know which wires to test. Valve switches from tank to tank just fine.

    Pegging out over full usually means the ground side of the circuit has been lost. The ground side should use a black wire. Mine was broken close to the tank, I added a piece in and connected to the floor under the truck until I can locate another rear harness that hasn't been butchered like mine.
