Product Description

The Exergy Performance E04 10305 Sportsman CP3 Pump is the ideal upgrade for GM's 6.6L Duramax LBZ engine (2006-07) when you're looking for improved fuel delivery, longer RPM range, and reliability under demanding conditions. Built to flow where the stock CP3 begins to fade, this unit extends pump capability into high-RPM or tuned environments without requiring extreme modifications.

Installation pairs seamlessly with factory CP3 footprint: remove the original pump, install the Exergy unit, and ensure your fuel supply and system are up to spec. While this pump helps unlock improved performance and durability, verifying supporting fuel system components (lift pump, lines, filters) and calibration is essential for best results and safe operation.
