 Installation:
First slightly screw union nuts of high-pressure line (4) by hand onto fuel high-pressure pump and rail. Then tighten to torque and tightening angle.
Tension can otherwise arise at high-pressure line (4).

 In this connection, counterhold high-pressure fitting at fuel high-pressure pump. Collect escaping fuel.

Check

 Danger

Risk of explosion caused by fuel igniting. Risk of injury to skin and eyes caused by fuel spraying out at high pressure

Keep all ignition sources out of hazard area.
Do not carry out any work on system when it is pressurized.

AS07.16-Z-0001-01A

 Warning

Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running.

Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.

AS00.00-Z-0005-01A

7

Check leak tightness in visible area when the engine is running.

 Visual inspection only.
