Q: Fuel gauge not working.

asked by on

My fuel gauge is not working. It doesn't tell me how much fuel I have left.

Hello. This is a common concern typically caused by a failing fuel level sensor. The fuel sending unit is the term used to describe this component, and is generally found inside the fuel tank. The level sensor and fuel sending unit, which includes the fuel pump, are not always sold separately. Have a mechanic check the electrical circuits as well as perform service involving volatile liquids.
