Hi, could you do the same liquid/gas storage just for crossing pipes (+)?

Uh, I am not sure, maybe! Do you need it for circuit networks? Might this one be useful for your purposes?

I already have the Fluid Level Indicator installed. I just want to build your cool little liquid storage at the intersection of pipes, and not just on a straight line of pipes.

Ah, right! So you would like a similar storage tank, but with 4 pipe connections!

Well... I honestly don't think I want to do that. I think it could be nice too, but it's not a feature that is particularly important to me. Also, 3 connections might be fine, but 4 is going to ruin the visuals (which I don't have the time or skills to fix), and I actually care a lot about that in this case.

So, maybe I could be interested in creating a 3-way version of the tank (which is at least useful for corners and t-sections), but I need to think about it.

3 connections would be nice too!

Good to know! I will look into it when I have the time (probably within a few days), and see if it is doable and something I want to make.

Thank you very much!

Hi again, I have just uploaded v.1.1.0, which contains a four-way variant of the storage tank! There were some finicky details, but it turned out to be easier than expected to modify the graphics and create something that looks decent enough. So anyway, here you go!

Thanks!

My pleasure!
