Dual tank selector valve

Dual tank selector valve
I have a 92 5.0 and I having issues with the dual fuel selector valve or Dual Function Reservoir as is the correct name. I replaced the dashboard switch but the guage still does not read fuel level from one tank to the other. Has anyone replaced the valve? Perhaps send pics.

I would agree with that - the wiring harness between frame and tank tends to get brittle over time on these trucks, and usually if the guage doesn't work, it's because of the sending unit mounted in the tank with the fuel pump assembly.

The only valve I'm aware of is a check valve on each tank so that when you switch tanks the gas doesn't go to the other tank. All the fords I owned from 91 to 96 has a sending unit in the tank with the pump. I have changed this before and it fixed a problem similiar to yours. I had fuel level at one tank but not the other. I find it odd that they both would go at the same time. This makes me think it's a wiring problem like the others said.
