When using mystcraft it will generate worlds with any liquid in the forge dictionary, tried using a pump on in but client crashed in single player when not connected to anything (without crash report). Hooked up to a smeltery it doesn't crash but doesn't pump it in.
Pumping out with just a pipe works as expected and back also works.

Forge 9.10.1.871
Build craft 4.1.0

I don't think this is a bug. You can't even pick up the liquid metals with vanilla buckets, even though there are buckets with said liquids in creative tabs. I think that's a bug on mystcraft side.

We managed to do it, you just have to find a full source block. But pumps dosnt work when I made 2 deep full blocks in a single player test world (Had creative).

Probably not a BC bug.

You can pick them up with buckets, at least now you can. You can pick it up with buckets, and put it into BC tanks. You can put it into seared windows with a faucet, and drain them to make metal blocks.

Still, it would be reeeaaaaally nice if you could pump all those liquids with the BC pump.

IC2/GregTech advanced pump does remove those liquid blocks, but does not relay liquids either. I spent too much time trying to get it to work, when it seems that it does not, and only installed these to test :(
