7.10. FUEL SYSTEM
The tank, made from aluminum, is located behind the seats, below the baggage compartment. It holds 76
liters (20.1 US gal.), of which 74 liters (19.5 US gal.) are usable. The tank filler on the left side of the
fuselage behind the canopy is connected to the tank with a rubber hose. The tank vent line runs from the
filler connection piece through the fuselage bottom skin to the exterior of the airplane .
A finger filter is installed at the bottom of the tank. From there, the fuel is fed to the electric fuel pump, and
from there, through the middle tunnel to the fuel shut-off valve. From the fuel shut-off valve it is fed to the
firewall breach, and further to the mechanical fuel pump. From there, the fuel reaches the distribution
manifold and finally the float chambers of both carburetors. A return line runs from the distribution
manifold to the tank. Incorporated in the return line is an orifice.
A fuel pressure sensor is installed at the distribution manifold. As soon as the fuel pressure drops below
0.1 bar (1.5 psi), the fuel pressure warning light will illuminate.
