Given a modern industrialization tank (any tier), if you store it in a system which is ultimately hooked up to a vault from create, which already have a tank of the same tier but empty, the fluid of said tank stored will be replaced by a tank with the same amount of liquid, in the end you'll have 2 tanks or even more with the same amount of fluid.
