Hi,I just tested the fuel system and logic. I am wondering that there are no manual control of the crossfeed 2 and 3 valves and in flight the valves always remain open and the switches have no function - so I am not able to close the valves.But in case of a fuel leak is suspected all crossfeed valves must be closed to have a complete tank to engine situation.Thanks for your advice.AlfredLOWW

After that you can left click to open/close the valves.Hope I understood you question right.Good Luck!
