You can Select Your Vehicle to check if 23220-31600 fits your vehicle.

Inspect the O-ring inside the fitting and replace if damaged.

If there is no sound, you should check the EFI fuse and the circuit opening or EFI relay.

After installing the lifter during the fuel pump installation, the spacer gasket and lifter guide should be placed onto the valve cover, aligning the fuel pump bolt holes.

To begin, remove the sending unit assembly from the fuel tank and drain any remaining gasoline from the pump/sending unit. Place the pump/sending unit on a clean workbench in a well-ventilated area. For 2007 and earlier models (except the 2007 RX 350), carefully pry off the end cap from the lower end of the fuel pump/sending unit assembly and remove the rubber insulator from the lower end of the fuel pump. Then, remove the fuel pump inlet strainer by disengaging the locking tabs with a pair of screwdrivers. Disconnect the fuel pressure regulator from the fuel return jet tube hose and fuel filter, and remove the fuel return jet tube assembly by pulling it out of the retainer clip. Disconnect the fuel pump electrical connector and remove the fuel pump from the fuel filter assembly. Separate the fuel filter housing from the upper part of the fuel pump assembly by disengaging the four locking tabs. Detach the fuel level sending unit from the upper part of the fuel pump assembly by disengaging the locking tangs from the lugs on the upper part of the pump.
