Twin CP3 Fuel System The CP3 High Pressure Fuel Injection Pump on the Duramax Engine is the key to power. Today's performance electronics can give you a lot of power through increased amounts of fuel being delivered into the engine at an optimized time. However, many aftermarket power-makers have the ability to command more fuel to be delivered, at a higher pressure, than the Duramax stock fuel pump can physically provide. When the CP3 falls behind, you're not getting 100% of the power that those other modifications are capable of providing. This "performance" issue is made even more critical through the use of high flow fuel injectors. Only The ATS High Performance Twin CP3 Injection Pump kit is capable of delivering the fuel required for big, efficient power.

ATS' Twin CP3 Injection System
The Twin CP3 System incorporates a second CP3 injection pump and all the brackets needed to mount it on the engine, where it will provide a constant fuel supply. Regardless of the extra fuel demands placed on the pumps by performance electronics or injectors, you will not fall short on fuel again! A must for any truck owner looking to make power & get the most out of their other modifications!

Dual CP3 Injection System
The ATS system is a clean bolt-on kit, including a secondary high-performance CP3 Injection pump, a billet pulley wheel for the second injection pump, all the necessary fuel lines and supporting hardware and a new belt to drive it all. You also get an electronic controller to integrate everything seamlessly. This kit is engineered to have perfect fuel control from idle to maximum RPM!

As always, it is critical to support higher levels of power with upgrades to the drive-train.
