When draining fuel, care should be taken to
ensure that no fire hazard exists before starting
the engine.
A fuel tank selector allows the pilot to control the flow of fuel to the
engine, and is located on the left side wall below the instrument panel.
It
has
three positions: OFF, LEFT TANK and RIGHT TANK. The arrow on the
handle of the selector points to the tank which is supplying fuel to the engine.
The valve also incorporates a safety latch which prevents inadvertently
selecting the OFF position.
Normally fuel is supplied to the engine through an engine-driven fuel
pump. An electric fuel pump serves as a back-up feature. The electric fuel
pump is controlled by a rocker switch on the switch panel above the engine
control quadrant. The electric fuel pump should be ON when switching fuel
tanks and during takeoffs and landings.
Fuel quantity and flow! pressure are indicated on gauges on the
instrument pane\. There is a separate fuel quantity gauge for each tank.
