I do not know on which side the problem is so I'm reporting it to both.

CyclopsMC/EvilCraft#435

Below is a copy pasted issue linked above:

I'm trying to transfer blood from one dark tank to another through dimensional transceivers. Chunks are loaded, fluid transfer is enabled and set correctly, pipes are set correctly, I checked multiple times. It just won't transfer through the transceiver.

I tried extracting the blood from Tconstruct smeltery and it worked just fine, so I really don't know what the problem is.

Looks like I had 2 different types of blood in each tank, so EnderIO works as intended, I guess this can be closed.
