    have someone work the switch and feel to see if the valve is working, your guage works so the in cab part sounds ok

    if it reads way over full you`ve probly got an open wire, and those selectors are common, i had to change a couple in my 80` and i only had it 3 years!!

    Isn't there a solenoid in under the bed that can go bad? My 87 does exactly what his does, the gauge registers, but she aint pulling fuel from the right tank. Course, I suppose the difference would be his fuel pump's on the motor and mine's in the tank, right?
