Toyota 23221-03040 Fuel Pump Assembly

To remove the fuel pump/Fuel Level Sensor from a vehicle, first, relieve the fuel system pressure and disconnect the cable from the negative terminal of the battery. Then, remove the rear seat from inside the passenger compartment and the fuel pump/sending unit floor service hole cover. Disconnect the electrical connector and fuel line, and remove the retaining bolts before carefully withdrawing the assembly from the fuel tank. Disconnect the electrical connector from the fuel pump and remove the pump from the assembly, either by sliding the hose clamp up the hose or by removing the fuel-sending unit and fuel filler and prying up the housing snap-retainers in sequence. Finally, remove the clip securing the inlet strainer to the pump and inspect it for contamination before replacing it if necessary. To install the fuel pump/sending unit assembly, reassemble it in the reverse order of disassembly and connect the fuel line and electrical connector before completing the remainder of the installation in reverse.
