I examine screenshots that people post, and when I study them, I sometimes take notice of fluid conduits that cross, but don't connect. "How do they do that?", I wonder? Every time I place fluid conduits next to one another, they snap together automatically, usually with tragic results. LOL
Well... wonder no more!! I just found the answer in the Ender IO wiki while searching for an answer to some other problem I was having...
I'll pass this one along in case other people have the same issue. I'm kind of flabbergasted I never heard of this before, but if it works, it certainly explains all those screenshots...
It also explains why those screenshots are always using the see-thru "Pressurized Fluid Conduit" instead of the higher-tier "Ender Fluid Conduit", which was the other thing I wondered about. I had assumed it was due to material cost... but now I realize that has nothing to do with it.
"Right-clicking a basic or Pressurized Fluid Conduit with a filled fluid container (e.g. a Bucket) will lock the conduit to only accept this type of fluid."
I assume this means we can use filled cells, since gases won't go into buckets.
