To replace the fuel pump on a 2002 Buick Century Custom, start by disconnecting the negative battery cable and relieving the fuel system pressure. Then, remove the rear seat to access the fuel pump access panel, or, if necessary, lower the fuel tank for direct access. Disconnect the electrical connectors and fuel lines from the pump, remove the retaining ring, and replace the old pump with the new one, ensuring all connections are secure before reassembling. Finally, reconnect the battery and check for leaks before starting the vehicle.
