- Thorough checks
System features
- System pressure is reduced after 30 s.
- Fuel system has independent ventilation.
Operation
- Do not bend high-pressure line or install it under stress.
- Replace seals and stretch bolts.
- Tightening torque to be strictly adhered to.
Tests
- Perform engine test run → Check system for leakage.
- Check leak oil lines by hand for secure seating.
- Replace leaky components if all mentioned notes (tightening torque, new seals) were observed.
General:
- Stop plugs are available as a replacement part for the diesel injection system → See EPC. Repeated usage is not allowed.
