Hello, the operation of the fuel gauge is like this. The fuel level sensor receives a steady voltage input, and as the level changes the voltage output of the fuel level sensor change. The fuel gauge in the dash receives this signal and the gauge in the dash displays the fuel level. To see what has failed in the system, electrical testing must be performed. You may need the aid of a mechanic to perform electrical testing to see if it is the fuel level sensor, the fuel level gauge or a wiring concern.
