Little Giant Model 35-OM
I just won this pump on e-bay for $20US. It looks like it may be perfect for a 3/8" system (the size of the barbs on the intake and discharge) since it is a direct drive impellor pump designed for high backpressure. It's H-Q info is:
170 GPH @ 10'
140 GPH @ 30'
110 GPH @ 50'
Shutoff @ 81'
It is originally designed to be used in a pressure washer, but I think it can be adapted nicely to watercooling, and it would virtually guarantee greater than 2 gpm through your system, regardless of fittings used. I'll let you know how it is when I get it and have a chance to test it.
