    That tank should not build pressure at all…should it?

    Yes, they do build pressure. In order to comply with no-emissions laws, the tank has an one-way vent valve built in. It will allow air to enter the tank, but not escape. But an over-pressure valve will open before it blows up. Or so I’m told.
