I am using latest version of mekanism (8.1.3) and today I noticed that my Chemical Dissolation Champer was completely filled with sulfuric acid but my Chemical Infuser which is the input for this fluid keeping empty (there is no sulfuric acid overflow in there). I think this is a bug because my Chemical Oxidizer keeps wasting sulfur and the bar in my Chemical Infuser is still empty :-/.

I have found the problem ... I missed the fact, that the pipe which connect the devices can store gas too ... this can be closed
