When working on the fuel supply/injection system, pay careful attention to the following "6 rules": z Thoroughly clean all unions and the adjacent areas before disconnecting. z Place removed parts on a clean surface and cover over but do NOT use fluffy cloths (lint contamination)! z Carefully cover opened components or seal over, if the repair cannot be carried out immediately. z Only install clean components: Only unpack replacement parts immediately prior to installation. Do not use parts that have been stored loose e.g. in tool boxes. z When the system is open: Do not work with compressed air if it can be avoided. Do not move the vehicle unless absolutely necessary. z Make sure that no Diesel fuel runs onto the coolant hoses. Clean contaminated hoses immediately.
