Right now, you have to get a pattern or bucket and put it in the input slot and then it knows what kind of item to output.

A single block will provide crafting for every type of fluid in your me system. I don't really like this, I'm not a big fan of one block being able to do so much.

With that said, this will change so that a single fluid filler will allow 1 type of fluid to be filled and it will take 3 speed upgrades.
