Hey Dirty Moogler,

Hmm.. As for the order of the loop, if I recall correctl it should be like this:

Radiator > Pump > Koosah 1 > Koosah 2 > Pump > TDX

As for the need for two pumps, well.. really depends on teh size pump you get. If you use like a D4 / D5, I'm pretty sure one pump will be enough. I really used 2 pumps because I wanted smaller pumps, and being able to mount a pump on the cpu block is just cool The D4 I modded actually died So I have a very pretty Yellow Candy D4 pump that doesn't work.

Hope that helps.

SAD
