Rules for cleanliness

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

  • ◆ Thoroughly clean all unions and the adjacent areas before disconnecting.
  • ◆ Place removed parts on a clean surface and cover. Only use lint-free cloths!
  • ◆ Carefully cover or seal open components if repairs cannot be carried out immediately.
  • ◆ Only install clean components:
    Only remove replacement parts from packaging immediately prior to installation.
    Do not use parts that have been stored loose (e.g. in tool boxes etc.).
  • ◆ When the system is open:
    Do not work with compressed air if this can be avoided.
    Do not move vehicle unless absolutely necessary.
