Sveins answer below gave me a new topic.
After flights do you close or not main fuel selector valve?
I have elected to keep it always open!
I understand there is an other side also.
Anyway when it is always open I never forget to open it before take offs.
I tested and it is possible to make a fast take off with closed valve.
That means EFATO situation.
To prevent jamming or seizing I move it couple of times in a year between
ON-RESERVE-CLOSED
positions.
Other visions please.
