Clean Working Conditions

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

Thoroughly clean all connections and the surrounding area before disconnecting.

Place parts that have been removed on a clean surface and cover them. Do not use fluffy cloths!

Carefully cover over opened components or seal, if repairs are not performed immediately.

Only install clean components: Only unpack replacement parts immediately prior to installation. Do not use parts that have been stored unpacked (e.g. in tool boxes etc.).

When the system is open: Do not work with compressed air. Do not move vehicle unless absolutely necessary.
