    Helping a friend out with a problem. I'm looking for a wiring diagram for the factory dual tank setup for a 1980 K10 4x4.

    Problem is the valve dosen't switch over sometimes, and the fuel gage shows full on both tanks, regardless of fuel amount in the tanks.

    I need part numbers for the valve, and help figuring this out.
