Fuel Quantity; Fuel Tank Selection - Beechcraft Bonanza V35B Pilot Operating Handbook

FUEL QUANTITY

Fuel quantity is measured by float operated sensors, located in each fuel tank. These transmit electrical
signals to the indicator through selector switches on the panel that indicate fuel remaining in the tank
selected. There are sensors in each fuel tank connected to the switches and indicator.
The fuel level of the fuselage auxiliary cell may be read by switching the auxiliary fuel gauge selector
switch on the subpanel to Aux position.

FUEL TANK SELECTION

The pressure type carburetor returns about 3 gallons per hour of excess fuel to the left main cell
regardless of the cell selected. To provide space for the returned fuel, the left main cell should be used
to approximately half full before switching. If the engine is allowed to stop firing due to insufficient fuel
refer to the EMERGENCY PROCEDURES section for the Air Start procedures.
The fuel selector unit handle is located
forward and to the left of the pilot's seat.
Take-offs should be made using the left main
tank and landings should be made using the
main tank that is more nearly full. In no case
should a take-off be made if the fuel
indicators are in the yellow band or, with less
than 10 gallons of fuel in each main tank.
SWITCHING FUEL TANKS
When switching fuel tanks, if one tank is
allowed to run completely dry, it may be
necessary to place the mixture control to Full
Rich position and maintain fuel pressure with
the Auxiliary Fuel Pump switch to aid in
restarting the engine. Close the throttle as
necessary to prevent engine overspeed on
starting. As soon as the engine is running
normally, discontinue the Auxiliary Fuel
Pump and reset the mixture control.
