Diesel Fuel Injection System, Rules of Cleanliness

CAUTION: When working on the fuel injection system:
- Thoroughly clean the fuel line connections and surrounding area before disconnecting.
- Place parts that have been removed on a clean surface and cover them over with sheeting or paper. DO NOT use fluffy cloths!
- Carefully cover or seal opened components if the repair cannot be completed immediately.
- Install only clean parts:

Do not unpack replacement parts until just before they are installed.
Do not use parts that have been stored unpacked (e.g. in tool boxes, etc.).

- When the system is open:
Avoid using compressed air if possible.
Avoid moving the vehicle if possible.

- Make sure that diesel fuel does not come into contact with coolant hoses. If it does, the hoses must be cleaned immediately. Hoses that have already been affected by diesel fuel must be replaced.
