  NOTE: TECHNICAL INFORMATION 
  Always install the high pressure line or rail free of distortion. To ensure distortion-free installation of the high pressure line and to avoid damaging the thread, it must be possible for both nuts to be screwed on to the injectors easily hand force.
  NOTE: Description is for left component only. Procedure on the right side is identical.
• First insert the high-pressure rail at the high-pressure pump connection, then lower to the point where the ball heads are positioned inside the injector connections and the high-pressure rail is correctly positioned.
• Then tighten the nuts (1) on the injectors so they are hand-tight.
