Caution Loosen the rail and move it slightly. This makes it possible to mount the fuel injection line free of tension. The lines must not be bent or under stress. Long term this would cause the line to break. Note The following describes installing new fuel injection lines. If in‐ stalling fuel injection lines, which were already removed, then be sure to check the points listed in -item 5- . The procedure is otherwise identical. Installing the Individual Fuel Injection Lines (Cylinder 1 through 4, between the Rail and Fuel Injector) ⇒ “3.3 Overview - Fuel System”, page 311 . – Remove the new fuel injection line from the packaging, re‐ move the plugs and place the line between the rail and injector immediately. – First tighten the union nuts by hand on the fuel injection line without using tools. Make sure the line is installed correctly. – Proceed the same way with the other fuel injection lines, if necessary. – Tighten the rail, if necessary, again to the tightening specifi‐ cation. 3.
