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.

Remove the engine cover and unscrew the banjo bolt securing the crossover line to the front fuel rail. Screw the adapter into the rail and connect the fuel pressure test hose.

Remove the retaining bolts on 2006 and earlier models, or remove the retaining ring on 2007 and later models using a special tool. Carefully lift the assembly, angling it to protect the fuel inlet strainer and the sending unit float.

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