REMOVAL

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

WARNING: Cover the hose connection with rags 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.

INSTALLATION

1. Install a new grommet and O-ring to the injector.

3. While turning the injector to the left and right, install it on to the delivery pipe.

4. Be sure the injector turns smoothly.

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