Q: How Do I Replace Fuel Injectors and Fuel Rail?A: Depressurize the fuel system and disconnect the battery. Remove the engine cover and detach the vacuum hose from the fuel pressure regulator. Remove the fuel pulsation damper and disconnect the fuel supply line. Discard old sealing washers and disconnect the fuel return hose. Disconnect the electrical connectors from the fuel injectors and the fuel supply hose. Remove the fuel rail and injectors. Discard the old O-ring, cushion ring, and seal rings. Install new seal rings and coat them with engine oil. Reinstall the injectors and fuel rail assembly, reconnect the battery, and activate the fuel pump. Check for fuel leaks.
