Rules For Cleanliness
When working on the fuel supply/injection system, pay careful attention to the 6 following rules for cleanliness:
-
Thoroughly clean all connections and the adjacent areas before disconnecting.
-
Place parts that have been removed on a clean surface and cover them over. Do not use fluffy cloths.
-
Carefully cover or seal opened components if the repair cannot be completed immediately.
-
Only install clean components: Only unpack replacement parts immediately prior to installation. Do not use parts that have been stored loose (e.g.
in tool boxes etc.).
-
When the fuel system is open: Do not work with compressed air if this can be avoided. Do not move vehicle unless absolutely necessary.
-
Disconnected electrical connectors: Keep clean and dry. Connect only when dry.
