I have a new (4 months) Puma 300L with the standard coolant pump and need to upgrade to the 140 psi pump for insert drills. Does anybody know where to get a pump that is less than the 1400 dollars Daewoo wants for there upgrade. The drills need more GPM than the standard pump delivers.

or is the factory pump the best way to go??

I bought my 220A Lynx with the 140 psi pump and have not been sorry. It puts out a LOT of coolant

Don't know where you can get a cheaper pump, but you'll also need a larger breaker, which is included in Daewoo's price, I believe.
