Guidelines For Clean Working Conditions

When working on the fuel supply/injection system, pay careful attention to the following "5 rules" of cleanliness:

• Thoroughly clean the connection 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 is not performed immediately.
• Only install clean parts: Remove the replacement parts from their packaging just before installing them. Do not use parts that have been loosely stored or unpackaged (for example, in tool boxes etc.).
• When the fuel system is open: Avoid working with compressed air if possible. Do not move the vehicle if at all possible.
