Product Description

The Exergy Performance E04 10405 Sportsman CP3 Pump offers a reliable fuel system upgrade for the GM 6.6 L Duramax LMM (2007.5-2010). With enhanced internal components and optimized delivery capacity, this pump improves fuel flow and rail-pressure stability compared to stock units - making it suitable for upgraded trucks that stay in the moderate performance range.

Installation is straightforward: remove the factory CP3 pump, install the Exergy unit, ensure your lift-pump and fuel-supply meet recommended specs, and perform calibration/tuning as needed. Because this unit supports higher output than stock, verifying the engine code, fuel-system condition and compatibility before purchase and installation is essential.
