How do you change a fuel pump in a 1998 infinity qx4?

To change the fuel pump in a 1998 Infiniti QX4, first, relieve the fuel system pressure by removing the fuel pump fuse and running the engine until it stalls. Disconnect the battery, then remove the rear seat and access the fuel pump cover. Disconnect the fuel lines and electrical connectors, unscrew the pump assembly, and carefully lift it out. Install the new pump by reversing the process, ensuring all connections are secure before reconnecting the battery and testing the system.
