Clean Working Conditions

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

• Always clean connecting points and surrounding areas 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.
• Only install clean components: Remove the replacement parts from their packaging just prior to installing them. Do not use parts that have been stored loose (for example, in tool boxes etc.).
• When the system is open: Avoid working with compressed air if possible. Do not move vehicle unless absolutely necessary.
