I have a 12v gas gauge from chevyduty for my 1951 3100 and a 1967 Mustang after market tank with sending unit.
When my tank is full the gauge reads 1/2 full. When the tank is 3/4 full the guage reads full and when the tank is half full or less the gauge read way over full, in fack so full that the needle is buried.
I think that this is an ohm problem. Does anyone have any sugestions for me?
