I'm playing the 1.0.8 version of the ATM9 To The Sky-modpack. It uses Minecraft 1.20.1 and it's using Mob Grinding Utils 1.1.0 with Utilitix 0.8.19.

The absorption hopper isn't pushing more than 100 millibuckets of liquid xp into the experience crystal, as shown here. This screenshot also shows why it probably doesn't work: The Experience Crystal "oredicts" it to another experience liquid.

This bug was also mentioned on Utilitix' Github (here), but the user who took the time to find out why this issue exists, and even make a potential patch for it, didn't take the time to file an issue/PR.

Is this something you'd be willing to fix, or is this considered "not actually a bug"?
