FUEL INJECTOR REPLACEMENT
REMOVAL PROCEDURE
1. Remove the fuel meter body assembly.
2. Remove the injector assembly retainer (11) and the injector retainer lock nuts (10).
3. While pulling the poppet nozzle tube 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.
INSTALLATION PROCEDURE
IMPORTANT: Each injector is calibrated for a specific flow rate. Order the correct injector for the application being serviced when replacing the
fuel injectors.
1. Lubricate the new injector O-ring seals with clean engine oil.
2. Install the O-rings on the injector assembly (2).
