Hello again Stovebolters . . I have a fuel gauge issue.
Yes, I have read through most of the fuel gauge questions/answers from older posts. I did not see my issue addressed . . . when I turn on the dash key switch, the fuel gauge needle drops below empty, it does not register any fuel? I know there are at least 8 gallons in the tank.
I am guessing that the gauge is original (?) to the '51 2-ton truck. Old posts usually said that electrical issues and not the gauge was the typical problem. It was not working when I bought it because most of the truck wires had been shredded. After removing the seat today I checked voltage at the tank. It was only 1.53 volts. Battery, headlight and starter all showed 6.54 volts. ALL wiring on the truck was replaced with a new harness and anytime a wire goes through the firewall, floor or other metal area, the wire is encased with a rubber grommet. I read that when the gauge trim ring is painted (as I have done) the fuel gauge may not be properly grounded . . . I attached a temporary grounding wire to one of the threaded studs holding the gauge group to the dash to make certain the gauge is grounded.
So, I am at a loss . . the voltage drop at the tank, the needle drop when the key is turned on and the fact that this is the only electrical issue I have experienced since replacing the harness?!
Any suggestions will be appreciated . . . . thanks.
