Hi Dan,
What machine do you have ?
First thing i would do is change out the standard line to 5/8 ID Hose.
The flow will greatly increase,
Secondly i would look into some kind of filter to stop the nozzles from being clogged with chips.
Also, check out LMD-NC.com
We make coolant rings for the Tormach machines that give 360 coverage and work with the ATC
