| When working on the fuel supply/injection system, pay careful attention to the following “rules of cleanliness”: |
| l
| Thoroughly clean all unions and the adjacent areas before opening. |
| l
| Place removed parts on a clean surface and cover. Do not use rags that shed fibres! |
| l
| If repairs cannot be completed in one session, all parts and components that are left open should be covered or stored with the greatest of care |
| l
| Only fit clean components: only take spares out of their packaging just before assembly. |
| l
| Do not use parts that have been stored loose (e.g. in toolboxes etc.). |
| l
| If the system is open, do not apply compressed air if possible. Do not move vehicle unless necessary |
| l
| Also, be extremely careful not to spill petrol on the coolant hoses. If necessary, immediately clean the tubes. Damaged hoses affected must be replaced |
