I think I found the solution to this...
The VDB import puts the pivot at the corner of the bounding box. FumeFX puts it's pivot in the middle at the base. I needed to offset the position of the VDB by half of the FumeFX size, added to any global offset. So if my origioal fume sim is offset in space by say 100 units in XYZ, I offset the VDB by the same and Subtract half the size of the original Fume grid in X and Z ONLY. So in my case my grid is 50x50x50 in size, so I do the global offset to the VDB then subtract 25 in X and Z. The Y aspect is correct so you don't need to compensate.
Hope that helps somebody!
