  1. Remove the fuel meter body assembly. Refer to Fuel Meter Body Assembly Replacement .
  2. Remove the injector assembly retainer (11) and the injector retainer lock nuts (10).
    3. NOTE: Use care in removing the fuel injectors to prevent damage to the electrical connector terminals.
    The fuel injector is serviced as a complete assembly only.
    Also since the injectors are electrical components, these injectors should not be immersed in any type of liquid solvent or cleaner as damage may occur. Fuel injector cleaning is not recommended.
  3. While pulling the poppet nozzle tube downward, push with a small tip punch down between the injector terminals until the injector is removed.
