To replace the fuel pump in a 1990 Cadillac Eldorado, start by relieving fuel system pressure and disconnecting the battery. Next, remove the rear seat to access the fuel pump access panel, then unbolt the panel and disconnect the fuel lines and electrical connectors. Take out the old fuel pump and install the new one, ensuring all connections are secure before reassembling the access panel and seat. Finally, reconnect the battery and check for leaks before starting the vehicle.
