just a thought is it possible to make them 1 item and support both inline and 4-way. so kind of like how pipe work, we dont have to craft all the intersections.
edit: ah stupid me so it will become just 4-way lol. actually, is it possible to have an option to only have 1 tank at a time, either inline or 4-way.
Making an option for enabling just one or both of the variants shouldn't be too hard! I can take a look at it in the near future. (Changed title to reflect new request.)
Just uploaded v1.4.0! (Finally got around to it...) The storage tank variants can now be individually enabled. It was more demanding in terms of code than I expected, but I figured it out.
