at all times and the build-up of water and bac-
teria is prevented.
The fuel return line must be led into the top of
the tank, and must feed down to the bottom of
the tank on the opposite side from the suction
pipe. This prevents foam forming in the fuel
tank: the constant flow of fuel ensures that the
build-up of dirt, and thus cleaning expenses for
the tanks, are not incurred.
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 automati-
cally de-aerating one. See 'Bleeding' . Start the
engine and check the fuel system for leakages.
Fuel Filters/Water Separators
3 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 4.
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
must replace the filter element as soon as
possible.
Proceed as follows:
See illustration 5.
• Acquire a replacement filter element: VETUS
article code 2020VTR (standard model, with
a fineness of 30μ) or 2020VTB (with a fine-
ness 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 posi-
tion.
• 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 housing.
• Tighten the T-handle hand-tight.
Use NO tools to tighten the T-handle.
