Fuel supply
Fuel is always supplied to the engine from the fuselage tank, which is filled by the
optional wing tanks by means of an interconnecting line featuring a quick-
disconnect coupling at the root rib.
Fuel form the fuselage tank is fed via the fuel shut-off valve, a strainer, the
electrical fuel pump and a filter element to the injection system, which is connected
to the engine.
The fuselage tank is drained via the externally accessible drainage valve on the
left side behind the gear.
Venting
The vent line of the fuselage tank is connected to the expansion reservoir via a
pressure relief valve and a non-return valve.
From there, a line leads to the outlet of the vent line on the right side behind the
landing gear box.

the tank. The vent line of the wing fuel tank is connected to the expansion
reservoir in the fuselage via the connecting line at the root rib with quick
disconnect coupling.
Warning:
In order to prevent that the engine stops due to lack of fuel, the opening
of the vent line must never be taped closed!
