Fuel Delivery and Air Induction: Service Precautions

CAUTION: When working on the diesel injection system always follow precautions on cleanliness below

- thoroughly clean all unions and area near connections before disconnecting
- place removed parts on a clean surface and cover over. Use paper or plastic sheet. Do not use fluffy cloths
- components which have been opened or disassembled must be covered or sealed carefully if repair cannot be carried out immediately
- install clean components only
- do not unpack replacement parts until immediately before installation
- do not use parts that have been stored loose (for instance, in toolboxes)
- when fuel system is open, do not work with compressed air if this can be avoided or move car unless absolutely necessary
- care must be taken to avoid dripping diesel fuel onto coolant hoses. If this should occur, clean the hose immediately. Corroded hoses should be replaced at once.


NOTE: If a defect is found while inspecting the injection pump, then the entire pump must be replaced. Repairs are not possible, exchange only.
