2.8 FUEL SYSTEM
The fuel is conveyed to the engine carburetors by two electric pumps, which are fed by two separate electric
circuits. See Figure 2.8/1.
2.8.1 MAIN LINE
The fuel system's main line consists of a tank, a fuel filter, two electric pumps, two non-return valves and a
pressure regulator. The tank is part of the passenger seat. It has a capacity of 7 2 litres. Approximately 3
litres of fuel cannot be pumped.
NOTE:
The fuel gauge fitted to the M16C reads
‘FULL’ when the content of the tank is over 55 litres.
For fuel levels above 55 litres the pilot should verify the tank contents by use of the markings
on the rear of the tank.
The tank is fitted with a drain valve (located in the tank's lowest point) and with a float-type fuel level gauge
(fixed to the rear left wall).
The level gauge's electric circuit is fed with 12 V through the equipment circuit (bus), which is protected by a
10 A circuit breaker. The level gauge's fastening flange also houses the fuel line's pumping and backflow
connectors. The fuel is pumped through a stiff pipe located inside the tank, at the end of which a wide-mesh
filter is installed. The fuel is filtered by a filter fixed under the main undercarriage, along the structure keel.
Two electric pumps for fuel are assembled in parallel downstream the filter. They are fitted with non-return
valves.
The fuel line ends in the pressure regulator (located on the engine) and in the following tank backflow
line.
A banjo union is fixed to the pressure regulator. The fuel pressure indicator line is fixed to that banjo union.
