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.
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.
ATTENTION:Employ genuine ROTAX fuel pumps only, as the pump must
meet certain requirements.
