Cleanliness requirements when working with the fuel system
When working with the fuel system, the following rules must be carefully observed:
Before disassembling, thoroughly clean the connection points.
Place the removed parts on clean pallets and cover them. Use paper or foil for this purpose. Do not use rags!
Carefully close open parts, or install technological plugs if the repair will be carried out later rather than now.
Install clean parts in place.
Unpack spare parts only immediately before installation.
Do not use parts that have been stored without packaging (for example, in tool boxes, etc.)
If possible, do not work with compressed air when the fuel system is open.
If possible, do not move the car.
Caution: Fuel may leak when removing fuel system components. Fuel vapors are toxic and highly flammable, so ensure good ventilation of the work area and avoid open flames.
