INSTALLATION
1. Fuel injector ASSY installation (low pressure side)
(1) Apply gasoline to two new O-rings and install them to the fuel injector ASSY.
CAUTION:
Make sure that there are no damage or foreign matter in the O-ring grooves of fuel injector ASSY.

New O-rings |
(2) Install the fuel injector ASSY to the fuel delivery pipe.
CAUTION:
·Make sure that there are no foreign matter or scratches on the insertion portion of fuel delivery pipe.
·Be careful not to twist the O-ring.
·After the fuel delivery pipe is installed, make sure that it can be rotated relatively lightly. If it cannot be rotated lightly, remove the fuel injector ASSY and repeat the work after replacing the O-rings with new ones.
