located
at
the
base
of the

NOTE:
DO
NOT
remove
this
bleedscrew.
At
the
same

at
the base of
each
fuel injector

on
the
high
pressure
line
by
cranking the engine over
with the
starter
motor
and
when
fuel free of
air
flows
from
bleedscrew #4, stop cranking with the
starter
and
retighten bleedscrew

Again
crank the engine over with the
starter
until fuel spurts
between
the 5/8
11
nut
and
the
high
pressure
injector
line
at
the
base
of
each
injector
Bleed
Point
#5.
When
fuel spurts
between
the
line
and
nut
at
each
of these four points, stop cranking
and
re-secure these nuts
with the
5/8
11
open-end
wrench.
NOTE:
Extensive torque
is
not required
on
these nuts to properly
seat the
high
pressure injector lines to the base of the
injectors.
6.
The
engine
is
now
ready to
start.
Leaving
the
throttle
in the
FULL
OPEN
position
and
ensuring
that
the engine
STOP
lever
is
in
the
RUN
position
and
the transmission
is
in
NEUTRAL,
proceed to
start
the engine. Preheat
as
required
and
crank the engine over with the
starter.
Once
the engine
fires,
return the
throttle
to
IDLE
position,
and
ensure
that
proper engine
oil
pressure
is
achieved,
and
that
raw
water
is
being discharged with the
ex~aust.
Allow
the engine to
run
at
1000-1200
RPM
for five minutes, to
be
sure
that
all
air
has
been
bled
from
the fuel system.
NOTE:
When
routine servicing of the on-engine secondary fuel
filter
is
being accomplished, bleed points
#1
and
#2
should only
be
bled to ensure
that
all
air
has
been
removed
from
the system.
No
other bleed points
need
be
bled
at
this
time.
Owners
may
find
it
advantageous to
daub
white paint onto
each
of the bleed points,
so
if
an
unexpected
problem
arises requiring engine fuel system bleeding, these points
will
be
readily
visible.
