Description
signals
that
indicate fuel remaining in each tank. The indi-
cators indicate full
when
20 or
more
gallons
are in each
wing
tank.
FUEL
BOOST
PUMP
The electric fuel boost
pump
is
controlled by an ON-OFF
switch on the
pilot's
subpanel.
It
provides pressure
for
starting, taxiing, takeoff, climb,
landing
and emergency
op-
eration
in
cruise configuration. Immediately after starting
the fuel boost
pump
should be turned off to test
the
engine
driven fuel
pump.
ENGINE
PRIMER
The control for
the
engine
primer
is
located
directly below
the
master
switches on the left subpanel.
It is used to in-
ject
raw
fuel
into
the
induction
system for cold starts. After
use, secure the
primer
by turning
it
to
lock
it in the off
position.
FUEL
TANK
SELECTION
The fuel
selector
valve handle is located
on the
floorboards
between the
pilot
and copilot seats.
Takeoffs
and
landings
should be
made using the tank that
is
more
nearly full.
NOTE
On serials
M-2225
and after, or on airplanes
which
have
complied with
BEECHCRAFT S.I.
No.
1095,
a
fuel
selector stop
has been
added
to the
selector valve guard. The fuel selector
stop minimizes the
possibility
of
inadvertently
turning the
fuel selector
valve
to the
OFF
detent position. The
stop
is
a spring which
must
be depressed before
the selector
valve
handle can be rotated
to the
OFF position.
If
the engine stops
because
of
insufficient fuel, refer
to the
EMERGENCY PROCEDURES
Section
for
the
Air
Start
procedures.
