I'm unable to find a wiki, and the readme and ingame manual don't provide much details. For the life of me, I cannot figure out how to get the pump to get water into the fluid infuser. I can insert into a tank using the servos, but nothing seems to work for the fluid infuser. am I missing something obvious?

... You put a bucket?
Water bucket perhaps?
Also make sure it's fully pwoered.

You need to configure the sides of the fluid infuser with a screwdriver, make sure you're on the page for fluids and not items too.
