How do you replace a fuel pump on a 93 Buick Roadmaster wagon?

To replace the fuel pump on a 1993 Buick Roadmaster wagon, first, disconnect the battery and relieve fuel system pressure by removing the fuel pump relay and running the engine until it stalls. Next, raise the vehicle and support it securely, then remove the fuel tank by disconnecting the fuel lines, electrical connectors, and straps. Once the tank is down, remove the old fuel pump from the sending unit, install the new pump, and reverse the process to reassemble everything. Finally, reconnect the battery and check for leaks before starting the engine.
