See the attached screenshot and savegame:

I can walk straight up and pass between the chemical plant and its attached storage tank. I cannot do the same between e.g. pipe or pump and tank I don't expect to be able to walk over any fluid connection.

Thanks for the report.
In my opinion, this is not something, that needs to be fixed.

It's definitely not a show-stopper. It is however an inconsistency in behaviour that is not understandable

There is no inconsistency.

1. Most "building" entities need a passable space around them, so their collision box is set to be smaller than their tile footprint. If collision boxes of two entities overlap, the entities can't be placed in that configuration by the player. Touching counts as overlapping.

2. Pipes have a special logic that stops players walking through the planes of their fluid box connections, despite their collision boxes technically allowing the player to pass.

3. There are no pipes involved when you have a chemical plant building directly adjacent to a storage tank building. Therefore, you can pass, because it's just two buildings.

To prevent this once-in-a-lifetime occurrence from happening, every single pipe connection on every single entity would need to have the extra logic and runtime checks every time the player scratched their arse. The resulting UPS hit would likely generate a wave of complaints about megabase performance.

Another "fix" that everyone would hate and moan about would be to make adjacent chemical plants impassable.

Thank you for expanding on that.
