Expected Behavior

I should be able to pump out all unwanted / stuck fluids on the input side.

Actual Behavior

Creosite and other fluids that are inputted are stuck in the refinery and cant get pumped out?

Steps to reproduce

Im using the refinery to make duroplast resin.

But its now halfway filled with creosite oil and 4mb of acetaldehyde.

To make the acetaldehyde i need the refinery filled with ethanol and silver plates but there seems to be no way to get the creosite oil and acetaldehyde out.

So is there anyway of getting it out? because destroying the multiblock the whole time and lossing several buckets of creosite oil is just an insane waste.
