Fuel Injector: Removal and Replacement
Fuel Injector Replacement
Removal Procedure
Important: The engine oil may be contaminated with fuel if the fuel injectors are leaking.
1. Remove the fuel meter body.
2. Remove the injector retainer lock nuts (4) and retainer (3).
Notice: 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 fuel injector downward, push with a small tip punch down between the injector terminals until the injector is removed.
Installation Procedure
Important: When ordering new fuel injectors, be sure to order the correct injector for the application being serviced.
