You mention "pressure" several times, but don't forget that while the engine is running, the tank will be under a vacuum as the fuel is pulled out by the pump...

Some of the flexible rubber "bladder" types are designed to run ventless, and used that way on purpose. They just collapse internally when the fuel is sucked out. It's safer that way, as there isn't a pocket of fuel/air mixture inside the tank to explode, and the shrunken tank internals can be moved around more by an impact/deformation or even puncture of the metal outer shell, allowing the tank bladder to remain sealed and without spraying out the gas under pressure when the outer tank is deformed/crushed.
