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 of cleanliness:

• Thoroughly clean all connections and the surrounding area before disconnecting.
• Place removed parts on a clean surface and cover. Use lint-free cloths.
• Carefully cover opened components or seal, if repairs are not performed immediately.
• When the system is open, do not work with compressed air. Do not move vehicle unless absolutely necessary.
• Install clean components: Remove the parts being replaced immediately prior to installation of the new parts. Do not use parts that have been stored unpacked (e.g. in tool boxes etc.).
• Electrical connectors that have been disconnected: Protect from dirt and moisture. Make sure connections are clean and dry when reconnecting.
