Lexus 23814-20020 Fuel Delivery Pipe Sub-Assembly

To remove the fuel injectors, start by relieving the fuel pressure and detaching the cable from the negative terminal of the battery. Then, remove the PCV hose and the assembly that retains the Vacuum Switching Valve (VSV) control solenoids on V6 models. Disconnect the fuel injector electrical connectors and fuel lines from the fuel rail, and remove the fuel rail mounting bolts. Finally, remove the fuel rail with the fuel injectors attached and the fuel injectors themselves. To install the fuel injectors, simply reverse the removal steps and tighten the fuel rail mounting bolts to the specified torque. If reusing the same injectors, replace the grommets and O-rings.

To remove and replace fuel injectors in a vehicle, start by relieving fuel pressure and disconnecting the negative battery terminal. Remove the engine cover and air intake duct if necessary. For four-cylinder models, disconnect electrical connectors, and remove the fuel supply line and fuel rail mounting bolts. Lift the fuel rail and injectors as a single assembly, replacing O-rings if necessary. For V6 models, remove the strut brace and intake manifold. Disconnect electrical connectors, and remove the Vacuum Switching Valve mounting bracket. If removing the entire fuel rail assembly, disconnect the fuel supply line and crossover tube. For 2GR-FKS V6 models port injection replacement, remove the upper intake manifold, and disconnect the fuel lines and electrical connectors. For direct injection, remove the upper intake manifold and high-pressure fuel pump. Install new injectors and O-rings, then reassemble components in reverse order. Start the engine and check for leaks.
