Fuel Injector: Service and Repair

Fuel Injector:

Fuel Injector Removal:

NOTE:

a. The fuel injector is serviced only as a complete assembly.

b. Use care in removing injector, to prevent damage to the electrical connector on top of the injector, and nozzle. Also, because the fuel injector is an electrical component, it should not be immersed in any type of liquid solvent or cleaner, as damage may occur.

REMOVAL:

1. Disconnect electrical connector to the fuel injector.
2. Remove injector retainer screw and retainer.
3. Using a fulcrum, place a screwdriver blade under ridge opposite connector end and carefully pry injector out.
4. Remove the upper and lower o-rings from injector and in fuel injector cavity and discard.

INSPECTION:

Inspect fuel filter for evidence of dirt and contamination. If present, check for presence of dirt in fuel lines and fuel tank.

Fuel Injector Part Number Location:

NOTE: Be sure to replace the injector with an identical part. Different injectors with different flow rates will fit this unit, but are calibrated for different flow rates.

INSTALLATION:

1. Lubricate new upper and lower o-rings with automatic transmission fluid and place them on the injector. (Make sure upper o-ring is in groove and lower is flush up against filter.)
2. Install injector assembly, pushing it straight into the fuel injector cavity.
NOTE: Be sure the electrical connector end on the injector is facing in the general direction of the cut-out in the fuel meter body for the wire grommet.
3. Install injector retainer, using appropriate thread locking compound on the retainer attaching screw. Tighten the injector retainer attaching screw to 3.0 Nm (27.0 lb-in).
4. Connect electrical connector to the fuel injector.
5. With the engine OFF and the ignition ON, check for fuel leaks.
