How to Replace a Toyota Camry Fuel Pumpby Chris Moore
The fuel pump is the key component in sending the fuel from the tank to the engine. If you need to replace the fuel pump in a Toyota Camry, the pump unit is located inside the fuel tank directly below the rear passenger seats. You need to remove the seats from inside the car. Once they are removed the pump is easily accessible by opening a covered hole right above the tank. Unlike similar pump units, this assembly is modular, so you only need to replace the pump if the rest of the unit is still in good condition.
De-pressurize the Camry's fuel system. With the gas cap open (to release pressure in that location), open the fuse/relay panel under the hood and remove the relay labeled "C/OPN." Start the engine and let it run until it stops. Disconnect the battery's negative cable.
Detach the rear seat from the car. Lift up the front edge of the seat bottom cushion, disconnect the mounting bolt underneath and remove the cushion. Pull up the seat back locks, flip the seat backs down and remove the mounting bolts.
Remove the service hole cover from the floor under the seat concealing the fuel pump/sending unit.
Disconnect the fuel line and electrical connectors from the fuel pump unit. Remove the retaining bolts and withdraw the unit carefully out of the fuel tank.
Release the clips on the fuel pump assembly's plastic support with a screwdriver to remove the support. Then pull off the rubber isolator, remove the fuel sock filter and disconnect the electrical connector from the top of the assembly. You can now withdraw the fuel pump from the housing.
Connect the new fuel pump into place on the assembly housing. Reassemble the fuel pump/sending unit in order, from the electrical connector to the fuel sock filter, rubber isolator and bottom plastic support.
Place the pump unit back within the fuel tank and reattach the bolts. Reconnect the electrical connectors and the fuel line. Reattach the rear seats.
Replace the "C/OPN" relay, reconnect the negative battery cable and fill the fuel tank if it is empty.
Pressurize the Camry's fuel system by turning the ignition on for a couple of seconds. Then turn it off for ten and repeat this five to ten times.
