Awesome, thanks for the help guys, really appreciate it. That seems like an odd default value for the config file; if I'm interpreting it right, with that value set to false, steam funnels are useless, correct?
Also, I can confirm that changing it resolves the issue, and not only do fluiducts not need to be set to pump mode, they don't actually work if they're in pump mode. I had to tear all mine out and set them to default mode, then steam began to flow.
