Maintenance Manual
2.3) Fuel filter
There is a fine filter in the fuel supply line between tank and inlet to the two fuel
pumps.
â—† NOTE: The built-in filter on the suction side of the electric fuel pumps
cannot not be replaced.
2.4) Fuel pump (on 912 Series)
The engines of the 912 Series are equipped with a mechanical fuel pump. It is
driven via an eccenter in the propeller gearbox.
2.5) Fuel pump (on 914 Series)
To warrant safe and adequate operation of the fuel system, two independent
selfpriming vane pumps are used. The voltage supply to the two pumps must
be established completely independently.
â—† NOTE: Voltage supply to main pump directly from internal alternator
and supply to the supplementary pump from bus bar or battery.
For engine operation, the rate of delivery of one pump alone is
entirely sufficient.
â– CAUTION: Use only genuine ROTAX fuel pumps, as the pump must meet
certain requirements.
