I'm writing through a translator, so I apologize for any mistakes

Is it possible or is it already there, but I don't know how to make a more precise adjustment. I need the network to provide resources but not to take them away.

And something needs to be done to build the blueprints with the network, it's not critical, but it would be nice to make it work or replace the connectors with a 1x1 block, similar to connecting a pump to a train and placing it next to the building, where you can also configure the input/output settings.

I'll write here instead of creating another section. I'm playing with the Pyanodon mod, and as I understand it, if I connect the inlet pipe to the Pyanodon tank, the liquid won't flow into the network in equal amounts. For example, if there were 150,000 in the network only 30,000 were transferred.
