The design of the tank makes it sealed, the affect is twofold
Less octane is lost by volitiles escaping
Water is blocked from getting in
And the fact that it's fully sealed is painfully obvious when trying to fill, you have to hit a button to depressurize the tank before it releases the fill cap, a few times I've had to wait over a minute for the system to finish (usually when the tank was nearly empty and the temps were below zero)
