cells,
a decreasing
fuel
flow and eventual
engine stoppage.
Venting of
the
right
tank
is accomplisbed
by an interconnecting
line from the
left tank.
The
left
fuel tank
is vented
overboard
through a
vent line whioh
is
equipped
with
a
check
valve, and
protrudes
from tb.e bottom
surface
of
'the
left wing
near the
wing strut
attach
point.
The fuel
filler
caPs
are equipped
with
vacuum
operated
vents
which
open; allowing
air into the tanks'
should
the
fuel tank
vent line become
blocked.
Fuel
quantity
is measured
b;r two
float-type fuel
quantity
transmitters
(one
in each
tank) and
indicated',by
twqelectrically-operated
fuel
quantity
indicators
on tlre
right side of the
iastrument
panel.
An
empty
tank
is
indicated
by a red
line and the
letter E. When an
indicator shows
an empty
tank,
approximately
2.5
gallons'remain
in a
standard
tank or
long
range
tank
as unusable
fuel.
Tbe indicators
cannot be
relied upon for accurate
readings
during
skids, slips,
or unusual
attitudes. If both
indicator
pointers
should
rapidly move to a,
zero reading, check
the cylinder
head
temperature
gage
for
operation.
If this
gage
is not
indicating, an electrical
malfunction
has occurred.
'
The
auxiliary
fuel
pump
switch
is located on
the left side of
the
switch
and
control
panel
and
is a
rocker-t5rpe switch'
It
is labeled AUX
FUEL
PUMP.
When
the
pump
is operating,
it will r4aintain
fuel
pressure
to
the
carburetor.
It
should
be
used
whenever the indicated
fuel
pressure
f.aLLs
.
below
0.5
PSI, but
is not required
when
gravity
flow and/or
the engine-
(
driven
fuel
pump
can maintain
indicated
pressures
above 0.5
PSI.
\
The
fuel selector
valve should be
in the BOTH
position
for
takeoff'
climb,
landing,
and
maneuvers
that involve
prolonged
slips or
skids.
Operation
frorn either
LEFT or IiIGHT
tank is
reserved for cruising
flight.
NOTE
When
the
fuel selector
valve handle
is in the BOTH
position
in cruising
flight, unequal
fuel flow from each
tank
may occur
if the wings are
not maintained exactly
level. Fiesulting
wing heaviness can be.alleviated
gradu-
ally by
turning the selector
valve handl6
to the tank in the
"heavy"
wiug.
NOTE
It
is
not
practical
to measure
the time required,to
consume
all
of
the fuel
in
one
tank, and,
after, switchingr
to the
opposite
tank, expect
an equal
duration
from the remain-
ing
fuel. The airspace
in both
fuel tanks
is interconnected
by
a vent
line and, therefore, some
sloshing of
fuel between
tanks can
be
expected
when
the
tanks are
nqarly full
and
