Repair of the fuel injection system

When working on the fuel injection system, the following rules of cleanliness must be observed:

1. Thoroughly clean joints and adjacent surfaces before disconnection.

2. Fold the dismantled parts on a clean lining and cover them with film or paper, do not use rags for this.

3. Carefully cover open structures, do not leave them separated, since repairs are not being carried out.

4. Install only clean parts:

• Spare parts should only be taken out of the packaging immediately before installation..
• Do not use spare parts that have been stored unpackaged.

5. With an open system:

• Avoid using compressed air if possible.
• if possible, do not move the car.

In addition, you need to make sure that diesel fuel does not get on the cooler hoses. If necessary, the hoses must be cleaned immediately. Worn hoses must be replaced.
