Racor Filer Cleaning...Continued:
O
kay,
the
filter
unit
has
been
cleaned
and
we
are
finally
ready
to
replace
the
element.
Since
diesel
engines
generally
will
not
start
with
air
in
their
fuel
systems,
we
will
need
to
refill
the
filter
assembly
with
fuel.
A
note
of
caution
here,
I
have
seen
lazy
mechanics
actually
use
the
engine
to
draw
fuel
into
the
empty
filter
unit.
They
do
this
by
cranking
and
cranking
the
engine
until
the
fuel
fills
the
cylinder.
Since
the
engine’s
fuel
pump
and
injectors
are
lubricated
by
the
diesel
fuel,
running
these
components
dry
like
this
will
cause
unnecessary
metal
to
metal
wear.
This
procedure
is
totally
wrong.
Should
you
witness
your
mechanic
doing
this,
my
advice
is
to
give
him
the
Donald
Trump
exit,
“Your
Fired!”
The
best
method
is
another
trick
we
use.
Before
you
insert
the
element,
pour
fresh
diesel
fuel
into
the
canister
till
it
is
a
little
more
than
three
quarters
full.
Next,
gently
push
the
filter
element
down
into
the
unit,
taking
care
to
let
the
element
absorb
fuel
as
you
push.
Push
too
fast
and
fuel
will
be
displaced
over
the
top
of
the
unit.
Once
the
element
is
completely
down,
slowly
top
off
the
canister
with
just
enough
fuel
to
cover
the
top
of
the
filter
.
It
will
not
matter
if
there
is
a
small
air
gap
above
this
point.
Then
replace
the
lid
gasket
and
the
“T”
handle
“O”
ring
with
new
gaskets
found
with
the
new
filter
element.
Be
sure
to
coat
these
with
a
smear
of
fuel
to
insure
a
good
seal.
Refastened
the
lid
by
hand
tightening
the
“T”
handle,
and
open
the
fuel
valves.
You
have
done
a
great
job
and
are
ready
for
engine
start.
If
you
did
things
as
described,
the
engine
should
fire
within
a
few
attempts
with
no
need
to
air
bleed.
Let
it
run
for
several
minutes
to
be
sure
all
air
has
been
purged
and
you are good to go.
S
ome
final
hints,
there
may
come
a
time
when
you
might
be
at
sea
and
encounter
trash
or
especially
water
collecting
in
your
fuel
bowl
to
such
a
dangerous
level
that
engine
failure
will
become
eminent.
Sea
conditions
may
make
it
too
difficult
to
change
filters.
Generally,
I
have
found
that
one
can
open
the
bowl
drain
while
the
engine
is
running
and
remove
this
water/sludge.
Do
it
slowly
so
as
not
to
allow
air
to
enter
the
unit
or
an
air
lock
might
occur.
Practice
this
safely
at
the
dock
to
be
sure
it
will
work
with
your
particular
installation.
Finally,
let’s
say
you
are
in
some
dire
situation
and
your
Racor
filter
has
plugged
to
the
point
of
stopping
the
engine.
You
have
no
spares
or
cannot
do
a
filter
change
because
of
rough
conditions.
Removing
the
dirty
element
will
only
further
contaminate
the
fuel
in
the
unit.
What
can
one
do?
Look
closely
at
the
top
of
the
Racor
filter
element
and
notice
the
small,
approximately
quarter
inch
dimple
near
the
center
hole
(See
photo
6).
This
is
a
knockout
that
when
punched
out
allows
fuel
to
bypass
the
filter.
It
means
the
fuel
will
not
be
filtered,
but
it
might
keep
you
going
long
enough
to
get
home.
Add
all
this
information
to
your
hard
disk
of
boating
tricks.
Someday
they
may
save
your bacon.
