The inner fluid seal should not leak anymore than ANY other seal should leak such as wheel cylinders, calipers or any other master cylinder design over the last 70 years. Which means ZERO leakage, as in NONE.

Therefore the outer vacuum seal MUST get receive some tiny amount of lubrication from somewhere. I contend it gets that lube from the 'relief' port. And that is the SOLE purpose of the 'relief' port.

Perhaps my above claim is more or less just academic. Well maybe.
