In the fuel tank
To change the fuel pump in a 1989 Oldsmobile Regency, first, disconnect the negative battery terminal to ensure safety. Then, relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls. Next, access the fuel pump by removing the rear seat or the access panel, disconnect the fuel lines, and unbolt the pump from the tank. Replace the old pump with the new one, reassemble the components, and reconnect the battery before testing the system.
