I meant to add that the problem is no limited to high wing aircraft. I have seen the same thing happen on a Seneca. Mind you, that was because whoever refueld it had left the cross feed **** open. I think basically it is a case of making sure that you understand exactly how your particular fuel **** works. Not a problem I’m likely to be bothered by as the EV-97 has only one tank and a fuel **** that is either on or off.
