Maintenance Manual
3.4.7) Fuel pump (on 912 Series)
See Figs. 73-33, 73-39 and 73-40.
Depending on the engine configuration, it may already have been fitted
with a pump with fuel hoses, see Fig. 73-33.
On engines without fuel hoses, observe the aircraft manufacturer’s
instructions.
Check fuel hoses for scuffing marks and kinks. In the event of damage,
the complete pump with all the hoses must be replaced, as the hoses
are pressed in one piece with the pump.
Check pump flange (1) for planeness. If the pump plunger (2) shows
scuff marks, the pump must be replaced and the eccenter in the
propeller gearbox inspected. Check the connections (3) of the fuel
lines.
Pumps working at reduced power, for example as a result of contami-
nated valves or leaking diaphragms, must be replaced.
NOTE: A leaking diaphragm can be detected by the fuel
emerging from the ventilation holes (4).
The fuel sucked in is filtered by a fine screen integrated in the pump.
It is not possible to dismantle the fuel pump. If contamination of the fuel
pump is suspected, the pump must be inspected on the intake side (5)
using an endoscope.
NOTE: The consecutive (6digit) serial number is displayed on
the pump housing (6).
NOTE: Service Bulletins SB-912-049 “Checking eccenters
and fuel pump plungers”, latest issue must be ob-
served.
