3. Remove a protective casing (69), preliminary having noted its assembly position.
4. Disconnect from clips inlet (53) and pressure head (52) pipelines, and also a ventilating hose (66) with standard шланговыми clips. Mark hoses a sticky tape for simplification of installation.
5. Unscrew on the fuel pump the pressure head pipeline with a hollow bolt. The rests of the spilt fuel wipe a rag.
6. Remove an inlet hose, preliminary having weakened шланговый a collar.
7. Take a trunk floor sheeting.
