Attention : Water and contamination in the fuel system may lead to
losing power or engine failure. The pilot in command is to check the
fuel quality and the quantity before every flight.
Warning: A dirty fuel filter reduces the fuel flow to the engine and
leads to losing power or engine failure.
Leaks in the fuel system may lead to fire in the engine compartment.
3.5 The fuel system
The standard configuration includes one anti-explosion tank with a
capacity of 34 l. The tank is built in front of the fire wall beside the
passenger seat. It includes a fuel level sensor and is connected to the
filling neck on the right side of the gyrocopter. The fuel supply line is
connected to the tank in the lower back corner and leads to the fuel
pump(s) through a fuel filter. The supply line contains a drain valve at
the lowest point below the engine compartment. Excessive fuel is lead
back to the tank via return line, which connects to the tank on its upper
side. A vent line is also connected to the upper side of the tank.
An auxiliary tank is optionally built in the left side of the gyrocopter. It is
identical with the standard tank. In such a case, both tanks are
connected together through the fuel supply line. Fuel is supplied from
both tanks equally via a T-piece at the lowest point of the line between
the tanks. The vent line is also connected to the auxiliary tank.
Rotax 912 is equipped with a mechanical fuel pump while the fuel is
supplied to the type 914 by an electrical pump fixed on the fire wall in a
lower level than the tank. Both G 4-2 may be optionally equipped with
an electric auxiliary fuel pump, which is then fixed on the lower part of
the fire wall. The auxiliary pump may only be operated by the pilot in
emergency cases. The switch is in the instrument panel.
Fuel filters are to be inspected in every scheduled maintenance and
must be exchanged every
250 h . Only original filters are to be used.
It is strongly recommended to inspect and clean the tanks every 500 h .
