Precautions during the work with system of fuel feeding / injection

During the work with system of fuel feeding / injection it is necessary to follow the following rules:

1. Carefully clear places of connections and areas adjoining to them before separation.

2. After removal of components put them in the pure place and cover with a film or paper. Do not cover a detail with rags!

3. The opened or sorted components need to be covered or isolated accurately if their repair cannot be carried out immediately.

4. Establish only pure details.

  – deploy the packed spare parts only before the installation

  – do not use spare parts which were stored not packed (for example, in a box for tools)

5. At open fuel system:

  – avoid use of compressed air where it is possible

  – do not move the car without emergency
