      What are the parts of a gas gauge?

      The gas gauge system can be broken down into three basic parts: gauge, sender, and circuit. A fault in one or more of these parts will lead to gas gauge failure. The sending unit is usually part of the Fuel Pump Module : a combination of parts that includes the fuel pump, fuel strainer, fuel filter, and fuel float.

      What should the voltage be on the gas gauge?

      Remove the fuel pump module so you can manipulate the float arm. At this point, with the key in the ON position (but without starting the engine), back-probe the connector and check for voltage. You should always have 5 V or 12 V on one of the pins. One of the other pins will be voltage feedback to the gas gauge.
