NOTE: Both fuel pumps have capacity 120 l/h. Due to different flow resistance of the return
lines from the T-connector 26 (Fig. 3. Fuel system schematic) to the return outlets
inside the right and left tanks with both fuel valves 7 and 8 open (Fig. 3), the fuel will
be pumped from one of the tanks to the other. Fuel will fill that tank completely and
will start escaping it via the vent tube. For that reason, it is not recommended to
operate the engine with both fuel valves open.
CAUTION! If air gets to the fuel lines then starting the engine may take quite a long
time (several dozens of seconds). For that reason it is strictly not allowed
to empty completely any of the fuel tanks in flight.
