Well,very good question... Didn't think about it!!!
I assume that it may workk anyway, in the sense of: Fluid are not mixed, but can propagate in tubes sequentially (One after the other). For example, when you use the mod "Recycle", it delivers different fluids in the same tube.
To be honest, I just tested that the system works technically, didn't check its relevance. So, if it doesn't make sense, I'l deactivate it.
Don't hesitate to give me your own experience about it!
