Clean Working Conditions

Even a little contamination can lead to faults. When working on the fuel supply and fuel injection system, observe the following guidelines for a clean working environment:

• Before loosening, connections and surrounding areas must be cleaned thoroughly with engine or brake cleaner, and then cleaned area must be dried completely.
• Plug open lines and connections immediately with appropriate protective caps.
• Place parts that have been removed on a clean surface and cover them. Use lint-free 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.
• Protect disconnected electrical connectors from dirt and moisture and only connect if dry.
