Fuel pre-filter. Inspection
This filter is equipped with a pressure gauge (1)
which indicates when it is time to change the filter
insert.
Change the filer inserts as recommended in the
maintenance schedule, or earlier if the pressure gau-
ge shows a negative pressure of 6-10 (in. Hg) at idle
or 16–0 (in. Hg) at full speed/loaded engine.
WARNING!
Working with, or going close to a
running engine is a safety risk. Watch out for ro-
tating components and hot surfaces.
Fuel pre-filter. Changing the filter insert
The fuel pre-filter/water trap supplied by Volvo Penta
is available in single and twin versions. The twin filter
inserts can be changed with the engine running, by
closing off fuel flow to one filter housing at a time.
Fuel flow is controlled by putting the handle (1) in the
following positions:
A:
Normal operation (both filters are connected).
B:
The left filter insert can be changed.
C:
The right filter insert can be changed.
