Pioneering a reliable modified CP3 pump did not come easy. Thousands of hours of research and development have gone into making our pumps what they are today. We found the limits on a durability test bench, not on customers vehicles. After the initial R&D was complete, each series of pump was subject to one final test in which we ran the pump at 4500 rpms and a pressure that far exceeded what the pumps will see in the field for 40 hours. A final inspection was done after this test to ensure no parts had significant wear. In production, each and every pump is tested throughout the entire operating range of the pump up to 4500 rpm and 29,000 psi to ensure 100% proper function before being installed into a vehicle.

Note: The Duramax 12mm Stroker CP3 pumps are an LBZ based pump with an LBZ fuel pressure regulator for max pump performance. Custom tuning and supporting modifications will be required. Primary fuel supply requirement for max pump performance: 150 GPH @ 8-10 psi per Pump.
