If the main tanks' fuel level is above the aux tank's level, won't the fuel seek it's own level and fill the aux tank's vent line to the level of the main tanks? I am not familiar with fuel tank venting requirements, but wouldn't a vent line full of fuel present a potential problem? Is an air gap required?
BTW - Great idea & appealing design
