Just replaced my original coolant pump with this one.

Great pump at a good price.
Mounting requires you to cut a 5 " hole in the top of your Tormach tank if you elect to use it ( I did), and raise the drain tank up by about 5/8" ( I used some scrap as spacers)
I now have more flow & pressure than I know what to do with - I'm using the original shower hose and 2 lock line hoses for delivery, each with a ball valve control - can finally cut pockets etc. without re-cutting my chips. Amazing difference.
Just FYI for those that might be interested
