Clean Working Conditions

When Working On The Fuel Supply/Injection System, Pay Careful Attention To The Following "5 Rules" Of Cleanliness: 

• Thoroughly clean the connecting points and the surrounding area before loosening.
• Place the removed parts on a clean surface and cover them. Only use lint-free cloths!
• Carefully cover or seal opened components if the repair will not be done immediately.
• Install only clean parts: Remove the replacement parts from their packaging just before installing them. Do not use parts that have been stored loose (for example, in tool boxes etc.).
• If the system is open: do not work with compressed air. Do not move vehicle.
