    Too much variation in the supply voltage.
    Install a voltage regulator, then adjust for empty reading with still some fuel left.

    Try running a separate neutral wire to a good ground while fiddling with it. Make sure the gage is for the correct voltage system.

    The voltage regulator in the gauge may be defective.

    Yep, test the gauge, it's simple.

    Get rid of the gauge and simply dip the tank.
