Fuel system Fuel system IMPORTANT! The whole fuel system is very sensitive to dirt and even very small particles. Foreign particles in the system can cause serious malfunctions. It is therefore very important that everything is as clean as possible when work is carried out on the fuel system. Before starting work on the fuel sys- tem, the engine must be washed. If possible, a hot water wash should be used. It is strictly forbidden to carry out any machining work or work with compressed air near an open fuel system. Be extra careful and always use clean, lint-free and dust-free clothes and gloves when working on the fuel system. Scania recommends using Tegera 848 gloves.
Clean tools before they are used and do not use any worn or chrome-plated tools. Material and flakes of chrome may come off. Clean connections and the surrounding area be- fore removal. When cleaning, cloths or paper which shed fibres must not be used. Use clean and lint-free cloths. Plug or cover the connections during removal. Also clean the connections before fitting the components. Removed components should be placed on a thoroughly cleaned, dust-free sur- face. Cover with a lint-free cloth. Checking fuel level Check the fuel level and top up with fuel as necessary. Note: The fuel system must be bled if the tank has been run dry. Refer to the Bleeding the fuel system section.
