FUEL SYSTEM
The airplane has 2 fuel tanks located each in the inside leading edge of each wing.
Each tank is equipped with a vent with an internal inlet at the inboard top of the
tank and the outlet underneath the wing. The Fuel tank outlet is equipped with
an internal copper mesh finger screen acting as a filter.
A drain valve is located in the lowest point of the each tank.
Tank outlets lead to a fuel selector valve situated on the central console in the
cockpit.
Fuel return lines return excess fuel supplied by the fuel pump to the fuel tank in
use.
The system is configured as in the diagram below.
