Multi-fluid train station?

[Malidictus]

I've been playing around with multi-cargo train stations all day today, and it's been a ton of fun getting them to work reliably (as opposed to manually fixing endless stuck trains). I was wanting to do something similar with fluids, but I can't quite wrap my head around it. Not even sure if it's possible. Hence why I'm here. Has anyone done this before? Google doesn't find anything - or maybe I suck at searching.

Obviously, I can't store all the fluids in the same tank/system like I could with cargo, so I'll need multiple tanks. Fair enough. But then, how do I control the fluid flow? I can't attach a wire to a pipe and shut it off on signal input like I can with a belt. I could use pumps, but those have incredibly limited throughput. I'm loading trains, so ideally I'd want 9 pumps' worth of throughput. I can get that by attaching the tank directly to the pumps via pipes. Space Age gave pipes functionally infinite throughput, after all. But then, that's a hard connection that I can't detach conditionally.

Is there even a decent way to do this? You know, other than attaching 9 pumps to every tank and then another 9 pumps to the train. And that's only 9 because I'm using trains with three cars. There has to be a smarter way of doing this. I've looked into valve mods, but those have the same limitations of limited throughput and... still no easy on/off control anyway. Not sure what to do here.

So, since the problem seems to come from an (output?) buffer in a pump that might have prevous fluid in it, what about a little mod to remove pump buffers? Could they still function? Or is a buffer necessary for flow, therefore also needing a bit of code to automatically purge (a minimum sized) output buffer?

Internally, pumps are just fluid tanks with some added rules. They can't function without an internal fluid storage. It's theoretically possible to mod additional outputs into their fluid box. Probably cause them to pump out of all ends, and it's probably going to look jank as hell. Food for thought.
