How do you drain the fuel out of the gas tank on a 1989 Mazda 323?

To drain the fuel from a 1989 Mazda 323 gas tank, first ensure the vehicle is parked on a level surface and the engine is off. Remove the fuel pump relay or fuse to prevent the fuel pump from activating, then disconnect the fuel line from the fuel filter or injectors to allow fuel to flow out. Alternatively, access the fuel tank through the fuel sender unit by removing the rear seat or trunk panel, and siphon the fuel out using a siphon pump. Always take precautions to avoid sparks and work in a well-ventilated area.
