You just need to not be asking your pump to fight through vapor-lock as well as pump viscous fluid. You probably would need to mod out the water-block a little too, but that's easy. If you can make it gravity fed and put the pump near the end of the return line that takes a lot of strain off the pump......Mine anyways.

I still don't think that DDC pump will handle straigt anti-freeze for too long. Mine was pumping but got really hot and flow slowed way way down. And this is with no waterblocks in the loop.
