InfiTech 2 includes Applied Energistics 2, right? You can pipe fluids to a Matter Condenser (or is that disabled in the modpack?). Also, I imagine suggestions in this thread would be for GregTech 6, while your mention of the fusion reactor implies you're using the fork known as GregTech 5 Unofficial, maintained here by Blood Asp.
I was not aware that the fusion reactor was in a separate fork, and I also did not know that the matter condenser could accept fluids, so I appreciate that. I suppose if it is intended that the matter condenser from AE should be used in GT packs for voiding liquids then there is no need for the liquid voidinator. But it will live on, in my hopes and dreams.
