How do you drop a gas tank in a 1996 gmc suburban?

To drop the gas tank on a 1996 GMC Suburban, first ensure the vehicle is safely elevated and supported on jack stands. Disconnect the negative battery terminal, then relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls. Next, disconnect any fuel lines, electrical connections, and the filler neck. Finally, unbolt the tank straps and carefully lower the tank, ensuring to support it as you do so.
