  • Gas guage reads backwards on 1956 Thunderbird

    When the fuel tank is full, the fuel gauge reads empty and goes toward full as fuel is used. The fuel sending unit has been changed twice. The ground has been checked. Fuel gauge has been taken out and checked. What is the problem? Thanks.

    Spouse says to try reversing the leads on the guage.

      Yeah, what Dot said.

      Or say "E" is for enough and "F" is for finished!

        Great response Bob!
        I have to agree with Dot & her spouse. The guage is wireing needs to be switched.

            Maybe a bad ground, my 68 did the same thing. I put three heavy ground straps on the car, fix the problem.

              I am leaning toward a bad fuel gauge or bad wiring. I am asking for possible solution to fix problem and I welcome your ideas. I have the best car restorer for 55-57 Tbirds , so this is not an easy solution.

                    If the Tbird gage works like the one in the video (above), polarity makes no difference.
                    In this case I would suspect a wrong sending unit in the tank.

                    Could not get the video to play using Microsoft Edge. Internet Explorer works.
                    Anyway, sending unit current heats an element that moves the fuel gage needle. Polarity is not important in the model shown.

                      Make the "E" into an "F", etc.

                        Drop fuel tank and put correct sending unit in.

                          Sounds like the "Twilight Zone". You may have a Poltergeist.

                            The restorer is Ted Rossi of Westminister, Co. The wires were reversed on gauge and no help.

                              Make sure you have the battery installed properly. Some cars will run with reverse polarity but won't charge etc. My first job at a Ford dealership in the mid 80s was to fix a reverse polarity issue on an old Dodge I believe. I think they ran positive ground unbeknownst to the owner.
