[0.18.30] pumps connecting between fluid wagon connectors

I had a pump that was between the normal pump connections on the fluid wagon - but I'am not 100% how that can happen in this case - maybe something with the speed the train enters the station
more research needed.

I found it - use this blueprint - you may rebuilt and refule two of the train elements.
in one direction everything is fine - after the trains turns its direction the connectors are really terrible offset.

This is one of the well known cases of pump missalignment when part of train is on curved rail. There is always one end of train that is decided to be a head of train and there is also vertical shifting logic that is implemented to "make gaps between rolling stocks on curves nice", unfortunately vertical shifting logic takes the difference between fluid wagon direction and head rolling stock direction and shifts fluid wagon gfx along rails based on some value that depends on angle difference.

wouldn't it be the easiest way to define the leading engine the head every time?
that would fix this issue.

Maybe it would fix the issue, but it would create a lot more issues requiring mods being told that direction of given train has changed because in LuaTrain there are values like front_stock, back_stock, front_rail, back_rail and a lot of others, that all would swap when changing direction.
