Hey all, I haven't posted much here, just read and leeched all the good info from all you water cooling guru's (thanks for that by the way).
I found a very kick ass 12v water pump that flows 240gph and only uses 3A constant. This pump is off of a Dodge Durango, sounds funny I know but check it out. I have procured one of these through my parts dept. Its made by Bosch and has a Mercedes symbol stamped on it. Diamler-Chrysler thing kicking in i guess, but I have had this thing running for 3 weeks now and its great. Totally quiet, self-priming and its 12v so it doesn't mess with my crt.

. I have done some searching and only found one resource on this pump. The Bosch number is Bosch PA 66 - GF 30. The pa number is the motor and the ga number is the pump housing. The link I found with a pic is here:

For some reason that link has specs for the pump, but the pic is incorrect. They show two different pumps in the list. The correct pic is the one for the jabsco. Its relatively small.
Well If you have any questions, I will try to answer them. I could be a little more specific on where to get these pumps and some prices, I think it would be possible to get them from a salvage yard for next to nothing. Steve.
