Hi, Anonymous you could have a faulty sending unit or gauge, there could be a problem with your wiring. On models with the fuel gauge posing as a left-hand fuel cap the gauge is a press fit do not try to unscrew it, simply ample force lift up in a rocking motion to remove gauge. Disconnect wires to the gauge and with a set of positive and negative jumpers from the battery connect the positive jumper and flash the negative, gauge should peg full, if not replace the gauge. With a test light check for power to the sending unit, then remove the sending unit and manually operate the float arm slowly with the correct wiring hooked up to the fuel gauge and sending unit and the ignition on, the gauge should respond accordingly if not replace the float arm assembly. If your fuel gauge registers the incorrect amount of fuel in the tank you can try bending the float arm the necessary amount for a more accurate reading.
