I tried making it in both it's simple and advanced forms and it simply wouldn't work. I'm using the most recent version of Mekanism and Forge. Did the structure simply change or is this a bug?

Does it emit red particles? If not try not putting ports on the corners or edges

The structure didn't change unless you have valves in the edges and are talking about since 1.15 because in 1.15 it was bugged and allowed for valves on the edges. Though saying most recent of mekanism and forge provides no information... We want numbers

lol sorry pup didn't see you

It was the corners thing. God damnit. Thanks.
