6. Loosen the bolt (3) and remove the protective cover of the fuel rail.
7. Disconnect the connector (4) of the fuel rail pressure sensor.
8. Disconnect the fuel temperature sensor connector (5).
9. Disconnect the connector (6) of the flow control solenoid valve.
10. Disconnect the connectors of all glow plugs.
11. Disconnect the connectors of all fuel injectors.
12. Disconnect the clamps (7) of the injection control wire.
13. Unscrew the nut (8) from the injection control wiring bracket.
14. Move the electrical wiring to the side
15. Unscrew the nuts (9) and remove the fuel rail protection.
16. Clean the high pressure fuel line connectors between the fuel pump and the rail.
Caution: To avoid corrosion or damage, it is necessary to take measures to protect surfaces that may come into contact with leaking fuel.
17. Unscrew the nuts (10) of the fuel rail.
Caution: When loosening the high-pressure fuel lines, be sure to hold the intermediate joint with a wrench. Be careful not to damage the return fuel line of the fuel injectors.
18. Remove the high-pressure fuel line (11) between the high-pressure fuel pump and the fuel rail.
19. Place suitable plugs on the high pressure fuel pump and fuel rail port openings.
Installing a high pressure fuel line
Attention:
- Before installing a new high-pressure fuel line, it is necessary to lightly lubricate the threads of the nut with oil from the tube supplied in the new repair kit.
- Be careful not to let oil get inside the fuel line.
- Do not lubricate high pressure fuel lines supplied without a tube - these fuel lines are already lubricated.

Attention:
- Remove plugs from components and remove components from packaging immediately before installing the component.
- Be sure to replace the high-pressure fuel line between the fuel pump and the rail with a new one after each removal.
