Note t
| Safety precautions when working on the fuel supply system → Chapter. |
Caution t
| For easier installation of the fuel high pressure pipe, release the tension of the fuel distributor. If necessary, slightly push the fuel distributor. |
t
| For easier installation of the injection pipes, release the tension of the fuel distributor as well as the clamping claws of the injection units. If necessary, slightly push the fuel distributor and slightly twist the relevant injection unit. |

| The pipes must on no account be bent or installed when under tension. The installation tension can lead to fracture of the fuel high pressure pipe. |
|
Note t
| It is not allowed to use tools for aligning the fuel distributor/the injection units. |
t
| Pay attention to the cylinder specific marking when re-using the high pressure lines. |
t
| The high pressure lines can be re-used if: |
l
| The sealing cone of the relevant high pressure line is not deformed or cracked. |
l
| The line boring is not deformed, constricted or damaged. |
t
| Corroded lines must no longer be installed. |
