  3. GM5064709Courtesy of GENERAL MOTORS COMPANY
    CAUTION:

    During the installation of the fuel rail and injector assembly, ensure that the fuel injectors are positioned straight into the injector opening. Failure to follow this caution can tilt or bend the injectors and could cause leaks or malfunction after installation.

    NOTE:

    Use a fiberless, lint free swab to apply the lubrication to the O-ring before installation.

    Holding the largest diameter/body (2) of the injector only, insert the injector assembly (2) into the fuel rail. Ensure correct orientation of the electrical connector.

    4. CAUTION:

    Ensure the fuel injector retainer is properly installed. Failure to completely install the retainers may degrade fuel injection system performance or cause system malfunction.

    NOTE:

    DO NOT use any type of lubricant when installing the NEW combustion seals on the fuel injector tip.

    Install EN-51955-1  long protector (1) onto the fuel injector tip, covering the first recessed area closest to the tip. Place a NEW seal (2) on EN-51955-1  long protector (1).

  7. Using EN-51955-4  pusher (3), install the seal (2) into the recessed area (4) of the fuel injector, then remove the EN-51955-1  long protector.
  8. Compress the seal (2) using EN-51955-3  pre-sizer (5).
  9. Using EN-51955-5  sizer (6), resize the seal.
  10. Install EN-51955-2  short protector (7) onto the fuel injector tip. Place a second NEW seal (8) on EN-51105-2  short protector (7).
  11. Using EN-51955-4  pusher (3), install the seal (8) into the remaining recessed area (9) of the fuel injector, then remove EN-51105-2  short protector.

  13. Using EN-51955-5  sizer (6), resize the seal.
  14. GM2918356Courtesy of GENERAL MOTORS COMPANY
    NOTE:

    The fuel injector seals must fit properly in the relative groove. Overlapping of the fuel injector seals with the external surface of the injector must be avoided. Avoid handling the injector tip seals as much as possible to avoid damage.

    Check both of the fuel injector combustion seals on each fuel injector for correct seat:

    • The seal must not be too large, buckled, or corrugated (1)
    • The seal must be fixed tight and accurate (2)
  15. If the seals are not installed correctly, remove the incorrect seal and replace with a NEW seal.
