Removal Procedure
IMPORTANT:
The engine oil may be contaminated with fuel if the fuel injectors are leaking.
- Remove the fuel meter body. Refer to Fuel Meter Body Assembly Replacement .
- Remove the injector retainer lock nuts (4) and retainer (2).
- While pulling the fuel injector downward, push with a small tip punch down between the injector terminals until the injector is removed.
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.
