Take a read at the link I provided, I think you will find it very helpful.
The low pressure regulator (LPR) has a very specific purpose as it relates to the cocking mechanism. Switching to a pump will eliminate the need for the low pressure regulator. (You are will now do the work).
The high pressure regulator (HPR) is very important to firing paint and velocity control. Within that space you can operate withi two ranges of operating pressure.
I hope that helps a little. and I hope it wets your appettite towards the fun you can have tinkering with an A/C. There is a lot of configurations you can play with.
