Rules for cleanliness when working on the injection system
Even small amounts of dirt can cause faults in the injection system. When working on the fuel supply/injection system, pay careful attention to the following basic rules:
t  Carefully clean connection points and the surrounding area with engine cleaner or brake cleaner and allow to dry thoroughly before opening.
t  Plug open lines and connections with suitable protective caps immediately.
t  Place parts that have been removed on a clean surface and cover them over. Use only lint-free cloths.
t  Only install clean components; replacement parts should only be unpacked immediately prior to installation. Do not use parts that have been previously unpacked and stored away loose (e.g. in toolboxes, etc.).
t  When the system is open: Do not work with compressed air. Do not move the vehicle unless absolutely necessary.
