FUEL SYSTEM
While the engine
is
running, fuel
is
fed
from the fuel tank {optional part} through the fuel filter
to
the fuel pump, which feeds fuel to the injection pump. The injection pump then feeds the fuel
through the injection pipes,
to
the nozzles which inject fuel
to
the cylinders for combustion. Any
fuel leaking from nozzles
is
collected
in
the fuel overflow pipes which drain into the tank.

FILTER
A fuel filter
is
used
to
prevent dirty fuel
from
reaching the injection pump and injection nozzles.
The filter element will require occasional replacement
to
maintain
an
adequate flow
51
fuel
to
the
injection pump. The frequency of this service
will vary according
to
the cleanliness of available fuel
and the care used
in
storage.
