The fuel tank switching valve is where the valve is located. You need to replace the valve. That is the one where all the lines come together under the truck.
I attached a picture of the new valve and the location for you to view.
The fuel tank selector switch is a driver controlled device that controls which fuel tank the vehicle is operating from. It also controls the switching between the fuel gauge senders in the tanks.
Voltage from fuse 6 is supplied to the fuel tank selector switch when the ignition switch is in START or RUN. The position of the fuel tank selector switch determines the direction in which the fuel tank selector valve motor will move. It also determines which fuel tank sender will control the fuel gauge operation.
