I have a 1930 4-door sedan... fuel gauge does not work, suspect dash gauge. Units are removed. How would I trouble shoot this problem. Jim

With the sending unit removed you can test with an ohm meter one lead on the wire connection and the other on the housing, should be 0-30 ohm range. I like to test the dash unit by taking the wire off the sending unit and when you ground the wire the gauge will go to empty and the wire not grounded it should read passed full, if so the wiring and dash unit are fine. Be sure and check for voltage at the dash unit.

The sending unit is grounded by default through the mounting plate screws, through the tank to the frame of the car. You could always run a wire from one of the screws to the frame of the car, just to be safe.

It's not how fast you can go, but how good you look at 20 MPH.
