Fuel Supply

Clean Working Conditions

When working on the fuel supply/injection system, pay careful attention to the following 5 rules of cleanliness:

• Thoroughly clean all connections and the surrounding area before disconnecting.

• Place parts that have been removed on a clean surface and cover them. Use lint free cloths.

• Carefully cover or seal opened components, if repairs are not performed immediately.

• Install only clean parts: remove the replacement parts from their packaging just before installing them. Do not use parts that have been stored loose (for example, in tool boxes etc.).

• When the fuel system is open: avoid working with compressed air if possible. Do not move the vehicle unless absolutely necessary.
