Racor Filter Cleanig...Continued:
S
ome
technicians
will
disassemble
the
entire
Racor
unit
by
removing
the
plastic
bowl
and
turbine
assembly.
This
takes
more
time
and
parts
which
they
can
charge
you
for!
There
are
times
when
this
is
necessary,
but
I
do
it
only
when
there
is
no
other
choice.
Here’s
why
(See
Photo
4).
Four
bolts
attach
a
metal
ring
band
to
the
bottom
of
the
filter
unit.
This
band
holds
the
plastic
bowl
to
the
filter
housing.
In
this
band
ring
is
a
rubber
gasket.
This
gasket
usually
will
swell
up
once
it
is
free
of
its
positioning
groove
and
cannot
be
used
again.
This
expansion
is
due
to
contact
with
the
fuel.
It
is
very
frustrating
to
find
you
cannot
put
the
filter
back
together
with
the
now
oversized
gasket.
A
gasket
service
kit
is
available
for
this
situation,
but
why
spent
$30
bucks
unless
it’s
necessary.
Here
is
another
tip.
The
lid
for
the
filter
housing
has
a
rubber
gasket
in
its
under
side,
and
a
new
gasket
comes
with
each
new
filter
element.
This
gasket
is
the
same
as
the
ring
band
gasket
and
can
be
used
in
a
pinch.
The
lid
and
“T”
handle
gaskets
can
generally
be
used
more
than
once if you find yourself without a replacement.
A
s
I’ve
said,
I
seldom
remove
the
bowl
and
turbine,
but
if
there
is
evidence
of
thick
sludge
in
the
bowl
and
hanging
debris
from
the
turbine,
it
must
be
done.
The
reason
is
that
inside
the
turbine
assembly,
which
screws
apart,
is
a
small,
hollow
metal
ball
and
a
round
sealing
gasket
which
is
installed
smooth
side
towards
the
ball
(See
Insert
Photo
4
and
5).
This
device
serves
as
a
check
valve
to
prevent
fuel
back
flow
to
the
tank
whenever
the
engine
is
not
pumping
fuel.
The
check
valve
prevents
dirty
fuel
from
the
bowl
contaminating
the
tank.
If
there
are
heavy
deposits
of
sludge
in
the
filter
unit,
this
check
valve
can
become
clogged
to
the
point
where
it
cannot
function,
and
if
bad
enough,
can
completely
close
off
fuel
entry
to
the
filter
assembly.
If
the
Racor
needs
disassembly,
you
will
need
the
service
kit
so
all
internal
gaskets
and
seals
can
be
replaced.
These
kits
are
something
you
should
have
in
your
spares kit. Get them!
T
he
bowl
drain
is
typically
sealed
with
a
threaded
pipe
plug,
or
on
newer
models
a
plastic
petcock
which
permits
tools
free
opening
to
drain
off
water
or
sludge.
Often
these
will
plug
with
debris.
It
is
a
good
idea
at
each
filter
change
to
open
the
drain
and
insert
a
length
of
stiff
wire
or
tiny
screwdriver
blade
to
insure
the
drain
is
clear.
This
way
if
a
time
comes
when
things
are
less
than
ideal,
say
in
a
rolling
sea, you’ll have one less problem with which to deal.
