Do not re-install damaged high-pressure lines (1).
Fuel system leakage and environmental damage may occur otherwise.
- Tighten union nut (1a) and thrust piece (1b) on the high-pressure line (1) to the rear.
- Clean sealing cone (1c) of high-pressure line (1).
- Determine not deformed area of the sealing cone (1c) using a feeler gauge.
The not deformed area arises from the distance from the first measuring point (1M) to the second point (2M).
If non-deformed area is not at least 1 mm.
↓
Replace high-pressure line (1).
- Check diameter of thrust piece (1b).
This must be 10.2 mm before retightening. In the case of deviations in the diameter:
↓
Replace high-pressure line (1).
