MANUAL
In
an
injection-type
system,
most
fuel
malfunctions
can
be
attributed
to
contaminated
fuel;
therefore,
the
wheel-well-mounted
strainers,
finger
strainers
and
sump
strainers
should be
inspected
and
cleaned
regularly.
The
frequency
of
inspection
and
cleaning
will
depend
upon
the service
conditions,
fuel
handling
equipment,
cleanliness
and local
sand and dust
conditions.
NOTE:
If
Goodyear
fuel
cells,
manufactured
after
1961
(Construction
No.
ETC-39
BTC-54A
and
ETC-67)
are
installed,
no
preservation
procedures
are
necessary
when
the
cell
is
to
be
empty
for
an
Indefinite
pen~d
of
time. The fuel
cells should
not
be
open
to
the
atmosphere
except
for
the
normal
vent
lines
in
the
airplane.
Goodyear
fuel
cells
manufactured
prior
to
1961 and
Uniroyal
fuel cells
must
be
filled
every
10
days
or
the
walls
must
be
coated with
a
thin
coat
of
light
engine
oil.

every
100

FUEL
FILTER
NOTE:
Airplanes
TC-1406
and
After;
TE-847
and
After;
and
TH-176
and
After
do
not
have
the
heater
fuel filter
installed.
A
fuel
filter
is
installed in
the
nose
wheel
well
next to
the heater
fuel
pump
and filters
foreign
matter
from
the
fuel.
The
strainer is
equipped
with
a
snap-type
drain
and should
be
drained
daily
during
cold
weather
to
remove
accumulated
moisture
which,
if
allowed
to
freeze,
could
cause
heater
malfunction.

an
excessive

of
dust
or
sand
in
the
air.
