Fuel system
The engine fuel system is a so-called common rail-system. The advantage of the common rail-system is that the
engine control unit controls the timing and fuel amount, this mean better emission control and a smooth running
engine.
All work on the engine common rail-system must be carried out at an authorized workshop. Use only the recom-
mended grade of fuel, please refer to “Technical Data”.
WARNING! Fire risk. When carrying out work on the fuel system make sure the engine is cold. A fuel spill
onto a hot surface or an electrical component can cause a fire. Store fuel soaked rags so that they cannot
cause a fire.
Fuel filter. Change
1. Close the fuel valve/valves.
2. Clean the filter bracket and put a suitable vessel
under the filter.
4. Unscrew the filter, use a filter wrench if needed.
5. Clean the sealing surfaces of the filter bracket.
Make sure the filter is absolutely clean and the
sealing surfaces are undamaged. Moisten the
sealing rings with engine oil.
NOTE! Do not fill the new filter with fuel before as-
sembly. Contaminations may get into the system
and cause damage and malfunction.
6. Screw the new filter on by hand until the seal just
touches the mating surface. Then tighten a further
1/2 turn.
7. Open the fuel valve.
8. Vent the fuel system, see " Bleeding the fuel sys-
tem" in this chapter.
9. Start the engine and check for leakages.
