Rules For Cleanliness

Rules for cleanliness

Even a little contamination can lead to faults. Therefore when working on the fuel supply and injection system, pay careful attention to the following rules of cleanliness:

^ Before loosening, connections and surrounding areas must be cleaned thoroughly with engine or brake cleaner, and then cleaned area must be dried completely.
^ Seal open lines and connections immediately using suitable protective caps.
^ Place parts that have been removed on a clean surface and cover them. Use lint-free cloths.
^ Only install clean components: Only unpack replacement parts immediately prior to installation. Do not use parts that have been stored unpackaged (e.g. in tool boxes etc.).
^ Carefully cover over opened components or seal, if repairs are not performed immediately.
^ When system is open: Do not work with compressed air. Do not move vehicle unless absolutely necessary.
^ Protect disconnected electrical connectors from dirt and moisture and only connect if dry.
