Fuel pre-filter, draining water /
contamination
The pre-filter/water separator is installed between the
fuel tank and the engine and works in three stages –
Centrifugal separation, coagulation and filtration.
Water and impurities are collected in the bowl beneath
and can be drained through the drain valve. Place a
receptacle under the filter. Drain off water and
contaminants through the plug (D).
Changing the filter elements
Close the fuel cock on the tank and place a receptacle
under the filter before changing filter.
1 Undo the T-bolt (1), remove the cover (2) and take
out the filter insert carefully while turning it.
2 Drain off water and contaminants through the drain
plug (3).
3 Fit a new filter insert and fill the container with clean
fuel.
4 Change the gasket on the cover and the O-ring on
the T-bolt. Moisten the gasket and O-ring with fuel
before assembling.
5 Fit the cover and tighten it by hand. Wipe off any
fuel from the filter housing.
6 Open the fuel cock andmake sure there are no
leaks.
Twin fuel pre-filter/water separator
The twin filter is equipped with a pressure gauge (1).
The filter inserts must be changed according to the
maintenance schedule or earlier if the pressure gauge
indicates a vacuum of 6–10 inHg at no load or 16–20
inHg at full load.
Draining the filter
Place a receptacle under the filter. Drain off water and
contaminants through the plug (5).
