  Q: How to Properly Remove and Service the Fuel Pressure Regulator on Toyota Matrix?

  A:

  Before removing the fuel pressure regulator assembly on the 2AZ-FE engine model it is necessary to discharge fuel system pressure. You must first disconnect the negative cable before extracting the fuel suction tube assembly from the fuel tank component. The removal sequence for 4WD fuel components starts with taking out the fuel sender gauge assembly and then proceeds to the fuel pump after releasing its claw to detach the fuel pump filter hose and separating the claw at the jet pump nozzle while using a wrapped screwdriver to safely extract the jet pump and O-ring. To remove the fuel pump sub-tank use 2 claws but preserve the wire harness during the process of disconnecting the fuel pump harness connector. First remove the No. 1 fuel suction support along with the suction filter and fuel pump from the fuel filter while being cautious to avoid fuel pump filter or fuel filter damage yet avoiding suction filter removal. The O-ring should be removed from the fuel pump after disconnecting its connector. 2WD versions require the same procedure for fuel pump removal by releasing the claw before disconnection of harnesses and suction filter removal without inducing any damage. The removal process of the fuel pressure regulator assembly requires a screwdriver with tape protection on its tip to pull it slowly because it has a tightly installed O-ring and separation of the 2 O-rings from the assembly.

  Q: How to Properly Install a Fuel Pressure Regulator Pulsation Damper on Toyota Matrix?

  A:

  The installation of new O-rings should begin with applying gasoline or spindle oil before putting them on the fuel pressure pulsation damper assembly of the 2AZ-FE engine. The fuel pressure pulsation damper needs two bolts that should be tightened to 9.0 Nm (92 kgf-cm, 80 in-lbf) while inspecting that the O-ring remains intact without any displacement. The procedure begins with fuel main tube installation before continuing with air cleaner cap sub-assembly attachment along with hose and finishing with the No. 1 engine cover sub-assembly. Conclude the process by connecting the negative battery terminal cable then inspect for fuel leakage.
