Possible pump bug

[Ogro]

Greetings,

I am playing the experimental 2.1 and I encountered the following behavior that looks like a bug but I am not sure, so I am talking about here so other people can pitch in.

I made a new uranium mine to the SEE, and the sulfuric acid pipe was obviously too long, then I added a pump close to the first mine.
The game still shows alerts that the pipe is to long, but the mine started producing!? So I am just ignoring the alert.
Is that expected because of the new fluid system? Is this an alert issue? I am not even sure of pump effect range, so it is hard for me to tell.
I attached the game file if anyone wants to take a look.
