How do you drain the gas tank on a 1996 mercury mystique gs?

To drain the gas tank on a 1996 Mercury Mystique GS, first, ensure the vehicle is safely elevated and supported. Disconnect the fuel pump relay and start the engine to allow it to run until it stalls, which will empty the fuel lines. Then, remove the fuel tank by disconnecting the straps and any electrical connectors or hoses. Once the tank is free, you can access the fuel sender unit to drain the remaining fuel through the fuel line or by removing the sender unit.
