1947 Plymouth original gas gauge with a modern sending unit, It don't work
I have a 1947 plymouth with a 350chevy motor and it's a 12 volt system. the car has it's original gauge cluster including the original gas gauge. It also has a fuel cell I/o of a gas tank. I'm not sure what sending unit is in the tank but it's more modern than 1947. i can't get the gas gauge to register. Does anyone know of a solution for this besides buying new gauges?
