Fuel Injector: Service and Repair




REMOVAL
1. Release residual pressure from the fuel line to prevent fuel from spilling.

CAUTION: Cover the hose connection with a rag to prevent splashing of fuel that could be caused by residual pressure in the fuel line.

2. Remove the delivery pipe with the fuel injector and pressure regulator.

CAUTION:
(1) Be careful not to drop any injectors when removing the delivery pipe.
(2) Be aware that fuel may flow out when removing the injector.




INSTALLATION
1. Install a new grommet and O-ring to the injector.
2. Apply a coating of solvent, spindle oil gasoline to the O-ring of the injector.
3. While twisting the injector left and right, install it on to the delivery pipe.
4. Be sure the injector turns smoothly.




NOTE: If it does not turn smoothly, the O-ring may be jammed; remove the injector, re-insert it into the delivery pipe and re-check.
