Q: How do you remove the fuel rail and injectors?A: To remove the fuel rail and injectors, first you can relieve fuel system pressure and disconnect the battery. Remove the injector retaining clips and injectors from the fuel rail. To install new injectors, coat new O-rings with oil and install them onto the injectors.
