Made a pedestal added a bucket to it and hit the button to turn it on..
had a Metal Barrel from Immersive Engineering near the pedestal and nothing no fluid being moved at all.
Was trying to move a pool of lava.

If you have any idea's or help as to what's going wrong that would be great.

It does work with it but for whatever reason the IE barrel is coded so that the block that wants to insert fluid into it must be on the Y axis - that is above or below it. With that configuration I have just confirmed that it works.
