Rules for safety and cleanliness when working with the fuel supply system

When working on fuel supply systems, it is necessary to strictly follow the safety and cleanliness rules:

• Thoroughly clean the joints and places next to these joints before releasing them.
• Lay the removed parts on a clean base and cover with foil or paper. Do not use fluffy cloths for this!
• Exposed parts should be carefully covered or locked up unless urgent repairs are being carried out.
• Spare parts should not be taken out of the packaging until immediately before installation. Install only clean parts.
• With an open supply system, if possible, do not work with compressed air. If possible, do not move the car.
• Do not use any sealants containing silicone. Silicone particles sucked in by the engine do not burn and damage the oxygen sensors.
• Fasten fuel hoses to the engine only with spring clamps. The use of terminal clamps or clamps tightened with a screw is not allowed.
• Ensure that diesel fuel does not get into the coolant hoses. If fuel gets in, clean the hoses immediately. Replace hoses exposed to fuel immediately.
