Fuel prefilter change
Proceed only while the engine is shut down.
Should the filter be
fitted with a sensor to
detect the presence of
water (3), remove the
whole sensor from its
seat.
Remove the pre-filter by
unscrewing it.
Check that the new filter
has performance levels
that satisfy the needs of
the engine (e.g. by
comparing them with
the old one).
Damp the new filter seal with diesel or engine oil.
Hand screw the new filter into place until the seal gasket touches
the support, then lock by a further 3/4 of a turn.
Place the water presence sensor in its seat, taking care to couple
the threads correctly.
Loosen the bleeder screw (1) on the pre-filter support and activate
the hand pump (2) until the supply circuit is full. Ensure that any fuel
coming out is not dispersed into the environment.
Lock the bleeder screw tightly.
Start the engine and run it at idle for a few minutes to eliminate any
residual air.
Check the efficiency of the earthing connection of the filter support.
Note
:
Should it be necessary to accelerate the bleeding phase, the
hand pump can be used during start-up.
Do not fill the new fuel filter before positioning it on its
support, so as to prevent damaging impurities from
penetrating the furl circuit and injection system.
Eliminate the consumables and any materials in
contact with them (for example, filters) in
accordance with current regulations.
The FPT Technical Service Network workshops are
equipped for this purpose.
