Lexus 23220-0P030 Fuel Pump

Depress the release tab and pull up.

The initial steps to remove the fuel pump are relieving the fuel system pressure and disconnecting the battery.

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.

For four-cylinder models, you will need a fuel pressure gauge and T-fitting to measure the pressure.

The remainder of installation is the reverse of removal.

The options are to replace the entire assembly or disassemble it and replace specific components such as the fuel inlet strainer, fuel pressure regulator, fuel return jet tube, fuel pump, fuel filter, or fuel level sending unit.

To perform a fuel pump pressure check, you need to relieve the fuel system pressure.

During the installation, the high-pressure fuel pump bolts should be hand tightened.
