Absolute cleanliness is essential when working on high-pressure fuel circuit. Thoroughly clean the surrounding area of the separation point before opening the high-pressure fuel circuit. Only lint-free cleaning cloths may be used.
Even the smallest dirt particles in the hydraulic components can lead to malfunctions and a total failure of the high-pressure fuel circuit.
During reduction of the fuel pressure always wear oil-resistant, fiber-free gloves which are lined with rubber.
- Cover connecting point for the high-pressure line to be opened using suitable rags.
- Carefully loosen union nut somewhat for the high-pressure line to be opened.
No fuel should flow over the engine.
Otherwise damage will occur.
The pressure in the high-pressure fuel circuit is increased for an engine at operating temperature. Thus causes a larger fuel quantity to leak out.
Collect exuded fuel using a suitable absorbent rag.
