Rules for cleanliness
Rules for cleanliness
When working on the fuel supply/injection system, carefully follow the “5 rules” below:
t  Thoroughly clean all connections and adjacent areas before disconnecting.
t  Place parts that have been removed on a clean surface and cover. Do not use fluffy cloths!
t  Carefully cover or seal opened components if the repair cannot be carried out immediately.
t  Install clean parts only; remove replacement parts from their packages only immediately before installing them. Do not use any parts which have not been stored in their packaging (e.g. in a tool box).
t  Fuel hoses and pipes may be shortened only with a clean sharp knife. Cutting points must not be soiled or deformed. Cutting points and surfaces must be free of burrs.
