Fuel Filter
The fuel filter used is a Bosch disposable one mounted to the port side on the front of the
engine.
The filter cannot be cleaned, but has to be changed every 300 operating hours, or if water
contamination is suspected.
Unscrew the filter casing by hand after the filter casing has been emtied for fuel via the
drain screw in the bottom of the filter casing.
Before fitting of a new filter the sealing surface of the filter casing should be cleaned. The
filter casing should now be filled with clea fuel before it is screwed on and tightened about
half a turn after the sealing surface fits tightly.
After changing the filter bleed the fuel system by actuating the manual handle on the fuel lift
pump and pump until the fuel, free from bubbles, runs out at the vent screw on the top of
the fuel filter. Tighten the screw and loosen the fuel pressure pipes at their connection on
the fuel valves and pump again with the fuel lift pump until fuel, free from bubbles, runs out
from the fuel pressure pipes.
