Clean Working Conditions

Even minor contaminations can lead to malfunctions in the fuel injection system. When working on the fuel supply/injection system, pay careful attention to the following rules for cleanliness:

• Thoroughly clean all unions and adjacent areas with engine or brake cleaner and dry before disconnecting.
• Plug open lines and connections immediately with appropriate protective caps.
• Place removed parts on a clean surface and cover. Use lint-free cloths.
• Install clean components: Remove 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.
• Separated electrical connectors: Protect from dirt and moisture. Make sure connections are dry when reconnecting.
