- First insert the rail (2) at the high pressure pump connector, then lower it to the point where the ball heads are positioned inside the injector connections and the rail is correctly positioned.
- Then tighten the nuts (1) on the injectors so they are hand-tight.
- Next, hand-tighten the nut (3) of the high pressure pump.
- Lastly, mount screws (4) and hand-tighten.
- Tighten down screws (4).TIGHTENING TORQUES SPECIFICATION
