How do you drain a Hyundai excel fuel tank?

To drain a Hyundai Excel fuel tank, first ensure the vehicle is in a well-ventilated area and the engine is off. Disconnect the fuel pump relay to prevent the engine from starting, then relieve fuel system pressure by removing the fuel filler cap. Next, access the fuel tank by removing it from the vehicle, or use a siphon pump through the filler neck to drain the fuel. Always wear safety gear and follow local regulations for disposing of fuel properly.
