Ok so i talked to dean.
This is his recomendation:
[15:52] Dean: PMP-400 and there is a reservoir you can attach it to...
[15:52] Dean: then you just need to make an adapter to adapt the top hole..
Sounds like a plan if you want to attempt it.
If you do let me know, i think i can help ya walk you though it.
Or he recomends this:

And buy a DDC. He says that res takes a DDC. It seems like it would connect on the side.
Then you need to splice the 4 pin cable off the old pump and attach it to the DDC:
[15:56] Dean: there is a four pin molex in the exos that he can split a threepin off to power the pump
[15:56] Dean: and attach the DDC to that reservoir
Listen to dean... i trust him without batting an eye when it comes to Koolance.
