and repairs of the fuel system and for replacing the
preliminary fuel filter.
11.5 Replacing the Fuel Filter
Element
• Close shut-off-valve (1) at the preliminary fuel filter (2).
• Set three-way cock (3) (right engine side in driving
direction) to pos. II, so that the fuel runs out of the filter
housing. Collect fuel with a suitable vessel.
• Unscrew screw cap (4) with the filter element.
• Replace filter element and sealing ring.
• Screw in and tighten screw cap (4) with filter element.
Torque 25 Nm .
• Set three-way cock (3) to pos. I, so that the return line
is shut (as in initial position).
• Open shut-off valve (1) at the preliminary fuel filter.
For further information please refer to the
operating instructions for "Daimler Chrysler
Enfines" supplied (chapter Replacing the
Fuel FIlter Insert).
After completing maintenance and
repairs or replacing the fuel filter, the
tree-way cock must be turned back to
operating position, as with shut return
line and running engine pressure will
build up in this line which can cause the
line to burst. This results in a fire hazard
inside the engine bay.
To shut off the fuel supply, turn the shut-off
valve (1) to the left.
To open the fuel supply, turn the shut-off
valve (1) to the right.
