initial period of operation. At this time, there is a higher risk of
damage from foreign debris in the fuel system. Installations of
this kind (fuel feed pump in the external fuel system), generally
heavy fuel installations, must be equipped with a fine fuel filter
in the external system.
The element of the running in filter has to be removed after the
first 100 hours of operation and the running-in filter housing
should be left empty. The running in filter housing functions as
a damper for pressure peaks in the fuel system when the filter
element is left out.
If any kind of maintenance work is necessary on the fuel system,
between the engine and the fine fuel filter, it is recommended that
the running in filter is used for some (20 - 50) hours afterwards.
