Oh, you probably need a vented cap. Sorry. Just being a smart a$$. It really shouldn't build pressure in the tank, though. You can't be returning as much to the tank as you draw out even with EFI. Some of it gets used and therefore not available for return. If anything you should be creating a vacuum. In either case you need a vent somewhere in the system.
Hope my ignorance sheds some light.
