When you're pushing your 2007.5–2010 Duramax LMM hard—whether on the track or towing with high-power tuning—your factory CP3 fuel pump can quickly become a limiting factor. The Exergy E04-10406 10MM Stroker CP3 Pump solves that by delivering significantly more fuel volume, supporting over 850 rear-wheel horsepower, all while maintaining street drivability and OEM fitment.

This high-output stroker pump features a larger displacement 10MM cam designed to move more fuel per revolution. This allows you to hold consistent rail pressure at wide-open throttle, even with large injectors, aggressive tuning, or compound turbos. It’s perfect for tuned trucks, race builds, or serious performance enthusiasts who need reliable fuel delivery under extreme conditions.

Each Exergy pump is built and calibrated in-house using OEM-grade components and precision flow testing, ensuring your truck receives one of the most accurate and consistent high-performance pumps on the market. Installation is straightforward, with direct bolt-on compatibility with factory fuel systems.
