How do you take a fuel tank down from a 2001 Yukon XL?

To remove the fuel tank from a 2001 Yukon XL, first, ensure the vehicle is safely elevated and supported on jack stands. Disconnect the negative battery cable, then relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls. Next, disconnect the fuel lines, electrical connectors, and any mounting straps or bolts securing the tank. Finally, lower the tank carefully, ensuring to support it properly as you remove it from the vehicle.
