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.
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.
Ensure sufficient space above the unit
for replacement of the filter element. See
Drawing 3.
Pay attention to the flow direction. This is
clearly marked.
Bleed the fuel system, if it is not an auto-
matically de-aerating one. See 'Bleeding'.
Start the engine and check the fuel system
for leakages.
Maintenance
Draining water from the water sepa-
rator:
Drain monthly the water collected in the
water separator. If a large amount of water
is seen to collect in the transparent collec-
tion basin, you will have to drain it off more
frequently. See illustration 4.
Replacing the filter element:
Replace the filter element at least once a
Fuel Filters/Water Separators
year or every 200 engine hours, whichever
occurs the sooner.
If the vacuum gauge indicates a pressure
within the orange zone (-0.2 to -0.38 kg/
cm 2 ), you must replace the filter element as
soon as possible.
Proceed as follows:
See illustration 5.
• Acquire a replacement filter element:
Vetus article code 2020VTR (stand-
ard model, with a fineness of 30µ) or
2020VTB (with a fineness of 10µ).
• Open any taps that are still closed.
Close the taps on the filter that is to be
replaced. It is not necessary to stop the
engine.
• Loosen the T-handle and open the
cover.
• Slide the old element very slowly out of
the housing.
• Put the new element very slowly into
position.
• Fill the filter with sufficient clean fuel; by
doing this, you will not have to de-aerate
the system.
• Apply a thin layer of engine oil to the
O-ring and fit the cover to the filter hous-
ing.
• Tighten the T-handle hand-tight.
Use NO tools to tighten the T-handle.
Bleeding
Most engines nowadays are self-bleeding.
If this is not the case, you will have to bleed
the system yourself after having drained
off the water or having replaced the filter
element.
• Fill the filter with sufficient clean fuel.
• Apply a thin layer of engine oil to the
O-ring and fit the cover to the filter hous-
