Create pump filling an inw rold tank (10k buckets) for botmless hose pulley and making the fluid source infinite is destroying excess fluid in the filling when it should stop filling.
Then the pulley dont recognize the blocks.

Even when detecting the pump dont pump out anything. but if u revert the pump ot fill the pulley, it admits more buckets but destroys them if the 10k goal has been reached

Expecting: botomless biodiesel and pump pumping out infinite fluid

have tried sinking more blocks, 1 to the bottom and nothing works

If asked, have removed all fluids and i have more than 10k buckets. Did 2 times..

With the pool filled with lava works perfectly

Only water & lava can be bottomless in base create iirc.

as u can see in the screenshot it says bottomless with biodiesel...

Gonna guess that's a bug as it really shouldn't be bottomless AFAIK.
Do tell me if i'm just wrong.

i guess if the pulley shows bottomless then it is configured to allow all in the config...

In the Create config, fluids that are allowed to be extracted as infinite are Whitelisted, meaning it would need a manual change to add another. Afaik, Create can consider something Bottomless, but not pull infinite, as those 2 are different things.

This is the source for the bottomless config
allow.json

and this is the default value for the "allow.json"
{ "replace": false, "values": [ "minecraft:water", "minecraft:lava" ] }

So yeah, unless its manually changed, only water and lava work.
