supplied with the engine.
The fuel system includes two wing tanks of 40 litres each, a central tank of
6 litres, Fuel drain valve, fuel valves, a fuel filter, two fuel pumps and
connecting lines.
The fuel is gravity-fed from the right-hand or left-hand wing tank into the
central tank depending which wing tank fuel valve is open. The fuel is then
further directed from the central tank via the main fuel valve and fuel filter
into the serially connected two electrical fuel pumps which deliver the fuel
to the engine injectors.
The amount of fuel in each tank is indicated by a visual fuel gauge which is
a part of each tank. Minimum fuel quantity in the central tank is indicated by
a warning light on the instrument panel. The remaining fuel (4,1 litres), is in
that case enough for approximately 10 minutes of flight. The warning light
condition can be verified any time by pushing the control button. No red
light indication when the control button is pushed and held means the bulb
is blown out and the minimum fuel quantity is not indicated:- In this case,
make a more conservative estimate for fuel on board, check fuel quantity in
wing tanks and land as soon as you are not confident of the fuel quantity
inside the wing tanks.
Do not forget to properly manipulate the fuel tank valves to ensure
continuous flow of fuel to the engine.
The fuel drain valve outlet is behind the left seat on the outside bottom side
of the fuselage; to drain off water and dirt, the drain pipe is to be pressed
into the fuselage and subsequently a fuel sample is to be taken.
