Remove the fuel rail and the fuel injectors from the fuel rail. 10. Remove the four fuel rail insulators from the cylinder head. 11. If replacing the injector(s), discard the old injector, grommet, and O-ring. If only replacing leaking O-rings, remove and discard the old ones. 12. Further testing of the injector(s) is beyond the scope of the home mechanic. If in doubt, it can be bench tested for volume and leakage at a dealer service department. 13.
