Cylinder head
•
Adapter
•
Screws
•
Threaded areas
Position injector and insulator in the proper cylin-
der location.
IMPORTANT:
Be careful not to pinch any wiring
or hoses during assembly.
Lubricate mounting screw threads and under the
head of screw with a light coat of
Triple-Guard
grease. Install washers (one per screw) on injec-
tor retaining screws. Install screws and washers
through mounting flange of injector and thread
into cylinder head.
Tighten screws in stages, starting with the lower

First torque is 5 ft. lbs. (7 N·m)
•
Second torque is 10 ft. lbs. (14 N·m)
•
Final torque is 24 to 26 ft. lbs. (33 to 35 N·m).
Check condition of sealing O-rings on fuel mani-
