Hi, I need to inform you that the mod is very good but with little fluid in the system it suffers from several instability problems. Fluids cannot remain still in the pipe. and he is constantly emptying the pipe and filling it. as if it were continually pumping the fluid even in the pipes that are not pumps. Make a large grid of pipe and put 25k onyl fluid and them you will gonna see fluids fighting each other to fill the system going unintopable from 0 to 2.4k non stop filling and empting non stop on each section. like if each pipe was keep fighting as a pump from each other. But they should not work as pumps.
