9.2.1) Fuel filter:
➪ The coarse filter installed in or next to the fuel tank has to retain coarse
fuel contamination. It must allow opening for cleaning.
➪ In the feeding line between tank and inlet to the fuel pumps a fine filter is
located.
This filter is designed such that it can be inspected for maintenance. In
most cases this filter is part of a filter / water trap combination.
Filter has to be inspected at specified operating intervals. Clean or renew
filter as required.
➪ The built-in filter on suction side of the electric fuel pump is not exchange-
able.
9.2.2) Fuel pumps:
To warrant safe and adequate operation of the fuel system two selfpriming
vane pumps are used. The voltage supply to the two pumps has to be
established completely independent.
â—† NOTE: Voltage supply to main pump directly from internal genera-
tor and supply to the auxiliary fuel pump from bus bar or
battery.
For engine operation the rate of delivery of one pump only is
completely sufficient.
â– ATTENTION:Employ genuine ROTAX fuel pumps only, as the pump must
meet certain requirements.
