Fuel Filters/Water Separators
ENGLISH
For existing vessels:
(See illustrations B1 and B2):
Interpose the fuel filter/water separator in the
fuel supply pipe, between the fuel tank and the
fuel feed pump.
To avoid the fuel tank emptying out should
a leak arise somewhere in the fuel line to the
engine, a cutoff should be fitted near the tank’s
suction connection.
The following connection components are
supplied with the single version of the fuel
filter/water separator:
Two tank hose bosses — M16 x 1.5 — with
connections for 10mm hose and 3 M16 x 1.5
blind plugs.
All fine filters installed before or after the fuel
feed pump must remain in position.
Mount the filter housing against a vertical
bulkhead.
Ensure there is sufficient space below the filter
to allow separated water to be drained off; to
render visible any contamination in the collec-
tion basin; and to allow the filter element to
be replaced.
Pay attention to the flow direction. This is
clearly marked.
Bleed the fuel system, if it is not an automati-
cally de-aerating one. See ‘Bleeding’. Start the
engine and check the fuel system for leakages.
Maintenance
Draining water from the water separator:
Drain monthly the water collected in the water
separator. If a large amount of water is seen to
collect in the transparent collection basin, you
will have to drain it off more frequently. See
illustration 3.
Replacing the filter element:
Replace the filter element at least once a year
or every 200 engine hours, whichever occurs
the sooner.
If the vacuum gauge indicates a pressure with-
in the orange zone (-0.2 to -0.38 kg/cm
2
, -6 in
Hg to -10 in Hg), you must replace the filter
element as soon as possible.
Proceed as follows:
See illustration 4.
• Acquire a replacement filter element.
• For a single filter: Stop the engine and shut
off the fuel supply.
For a double filter: Open the taps on the
second filter. Close the taps on the filter that
is to be replaced. It is not necessary to stop
the engine.
• Undo the spin-off filter element with a dry
hand or a coarse cloth.
Use NO tools to tighten the replacement
filter.
• Loosen the screws with which the metal
protective basin is fixed to the filter ele-
ment.
Fix the metal protective basin to the new
filter element.
• Fill the new filter with sufficient clean fuel.
• Apply a thin layer of engine oil to the O-ring
and tighten the filter hand-tight.
