FUEL
CELLS
See Consumable
Materials
for
recommended
fuel
grades.
CAUTION
Never.leave the
fuel
cells completely empty
for
more
than
a
few
days,
as
the
cell
inner
liners
may dry
out
and crack,
permitting
fuel
to
diffuse
through
the
walls
of
the
cell
after
refueling.
lf
the cells are
to
be
left
empty for a
week or more, a
thin
coating
of
light
engine oil
should
be
sprayed
or flushed onto the inner
liner
of
the cells.
The Standard fuel cell
installation
consists
of
a
25-gallon
capacity fuel cell (22-gallon usable) and
filler
cap
in
each
wing
leading
~ge.
In the optional installation a
40-gallon
capacity fuel cell (37-gallon usable) replaces the
smaller
capacity cell. The
filler
neck in
this
installation
contains a
visual measuring tab to
permit
partial
filling
of
the
tank.
Filling the tank
until
the fuel touches the bottom
of
the
tab
indicates
27
gallons
of
usable fuel, and
filling
to
the
slot
in
the tab indicates
32
gallons
of
usable fuel. The airplane
must
be
level
for
the tabs to indicate accurately.

of
the fuselage. The
system
low
spot
drain
is at the bottom of
the
