In the last changelog update for 1.19.2 (0.8.0b) it said they were fixed, but I still can't do anything with them.
And also the fluids from this mod can't interact with the creative fluid tank.
But the mod itself is great.

Where is your pump jack?

I've built it several times in different ways, including how it's done in the guide, but it doesn't change anything

I have the same problem too, in survival and even in creative, version 1.19.2 (both 0.8.0 and 0.8.0b). Is there any update of this issue?

You need a pump jack. Don't forget to glue it.

Yes, it worked with the glue, thanks
