An excerpt from truck trend

"The CP3 is a radial-piston pump that can supply up to 29,000 psi in some applications and is perhaps the most well known and most modified high-pressure pump on the market."

"Next is the CP4, which is also made by Bosch. Although it has a higher number designation, the CP4 actually flows about 20 percent less fuel than its younger brother, the CP3. Found on ’11-to-present Power Stroke and Duramax engines, the CP4 is a more advanced pump despite flowing less fuel, with external high-pressure circuits and a maximum pressure of 29,000 psi."
