For safety reasons, I'd rather stick with the one-way vent cap unless someone has a problem. This thread is the first I've heard of fuel leakage. Considering that fuel pumps have a check valve that keeps 5+ psi in the system all the time, I'm a little suspicious of problems occurring with 4bbl-equipped cars. In order to get 5 psi in the tank, the (absolute) temperature in the tank would have to rise by more than 100 deg F.
