Rules of Cleanliness

Rules For Cleanliness
When working on the fuel supply/injection system, pay careful attention to the following "5 rules:"
- Thoroughly clean all unions and the adjacent areas before disconnecting.
- Place parts that have been removed on a clean surface and cover. Do not use fluffy cloths!
- Carefully cover opened components or seal, if the repair cannot be carried out 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 system is open: Do not work with compressed air if this can be avoided. Do not move vehicle unless absolutely necessary.
