Hey look its finally available for 1.20.1 !!! I even tossed in a few changes, and don't hold your breath but I'm considering a full redo.
- Updated to 1.20.1
- Tanks now will waterlog themselves if another tank is above them and waterlogged.
- Added the siphon and item that is crafted with a string and bucket. This item sucks the water out of a waterlogged block!
