INSTALL INJECTORS AND DELIVERY PIPES
NOTE:
- Be careful not to drop the injectors when installing the delivery pipes.
- Since the O-ring may be stuck to the injector, do not put a side load on it at the removal.
1. Install a new grommet to each injector.

10. Check that the injectors rotate smoothly.
  HINT:
  
  If injectors do not rotate smoothly, the probable cause is incorrect installation of O-rings. Replace the O-rings in that case.
