NOTES

Do not re-install damaged high-pressure lines (1).

Fuel system leakage and environmental damage may occur otherwise.

  1. Tighten union nut (1a) and thrust piece (1b) on the high-pressure line (1) to the rear.
  2. Clean sealing cone (1c) of high-pressure line (1).
  3. Determine not deformed area of the sealing cone (1c) using a feeler gauge.

    IMPORTANT

    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).

  4. 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).
