The fuel tank, as its name implies, is where the gas in a Jaguar XJ6 is stored. There are many components of a fuel tank, including the sensor that monitors how close you are to empty. Over time, the tank can rust or the valves that supply the tank can clog. When this happens, drain the fuel tank and remove it from your XJ6 so that you can clean the tank properly and restore it to full function.
Disconnect the negative terminal of the battery and set it aside.
Use a car jack to lift up your vehicle. Place jack stands under each wheel to ensure safety.

Remove the drain plug by rotating it counterclockwise. Allow the fuel to empty into the collection bin.
