02-04 Duramax ATS Twin CP3 Pump Kit

02-04.5 Duramax LB7

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.
