• Q: How to Service and Repair a Fuel Pressure Regulator on 2000 Toyota 4Runner?

  A: The first step toward fixing the fuel pressure regulator starts by removing the air cleaner hose together with the intake air connector assembly. Before working on the regulator remove the fuel return hose while placing beneath it a shop rag to absorb any fuel. Start by unfastening the holding bolt which maintains engine wire attachment on the LH cylinder head cover. Following this strip off the protector from its bracket located on the RH cylinder head cover and raise the engine wire from its position. The two bolts need removal and after pulling out the pressure regulator you can take off the O-ring. Use a light gasoline layer to lubricate a fresh O-ring before installing it onto the pressure regulator before fixing the regulator onto the LH delivery pipe. Check if the pressure regulator rotates without resistance because pinched O-rings may require removing and repeating previous installation steps. Secure the pressure regulator using two bolts while torquing them to 8 Nm (80 kg.cm, 71 in.lb) and reinstall the engine wire with its bolt. Secure the fuel return hose to the fuel pressure regulator by inserting it to the stopper and using the clip for attachment. Install the intake air connector assembly together with the air cleaner hose before conducting a fuel leak inspection.
