  17. Remove the fuel injector line retainers.

    18. Notice: DO NOT use compressed air to clean debris from the fuel injector inlet after the fuel line is removed. Using compressed air can allow debris to enter the fuel injector inlet and damage the fuel injector.

  18. Remove fuel injector lines.

Installation Procedure

    Object Number: 660502 Size: SH
  1. Install the fuel injector lines.

    2. Notice: Refer to Fastener Notice in the Preface section.


    Object Number: 1336209 Size: SH

    Notice: Ensure proper torquing of the fuel injector line. An under-torqued fuel injector line will not seal properly and an over-torqued fuel injector line may damage the fuel injector fitting. An improperly sealed or damaged fuel injector line or fuel injector fitting will cause a fuel leak.

  2. Tighten the fuel injector line fittings.
