Since all 3 parts of the wagons are considered seperate containers, when emptying the very last drops won't flow to the tank which it's extracting from.
Means I can't make a general purpose station.

If say, when merged, it was treated as a single tank 3x the size, and when split, split the single tank up, then it wouldn't be a problem.

From what I understood Rsending you might need to use 3 pumps to fully drain wagon now. It's something with rounding I think - not sure if it will be fixed to guarantee that fluid can go from left to right tank if you are draining from right side.

Yes, I believe if you pull from only one slot of a wagon, the last "unit" of fluid won't move to the segment with a pump because of how fluids are handled.

According to Rseding91 this is a side effect of the fluid wagons being 3 tanks. See 44656
