To replace the fuel pump on a 1998 GMC Yukon, first, relieve the fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls. Disconnect the battery and then remove the fuel tank by unbolting it and disconnecting the fuel lines and electrical connectors. Once the tank is lowered, access the fuel pump assembly, remove it from the tank, and replace it with the new pump. Reassemble everything in reverse order, ensuring all connections are secure before reconnecting the battery and testing the system.
