Have you tried opening up the gauge to see if it is moving smoothly
internally? I just went thru this on my 66 B. When you get the gauge out
you can put voltage across the terminals from a nine volt battery and watch
the movement. My problem ended up being the voltage regulator. If it was
installed on the firewall it would not let the gauge come above 1/4 full no
matter how much gas was in the tank. If I just let the regulator dangle from
the plugged in wires it works perfectly. I spent numerous hours on this and
know the system intimately.
Need any more help, just let me know.
