EXERGY E04 10504 IMPROVED STOCK CP4.2 PUMP 2011-2016 GM DURAMAX 6.6L LML

The EXERGY E04 10504 Improved Stock CP4.2 Pump for 2011-2016 GM Duramax 6.6L LML engines is the ultimate solution for those experiencing rail pressure loss due to a worn-out CP4.2 pump. Engineered to deliver optimal performance, this factory replacement pump is designed to cater to power levels up to 550+HP without the need for additional modifications or tuning.

What sets the Improved Stock pump apart is the inclusion of the System Saver Inlet Metering Valve, a game-changer in terms of durability and functionality. By replacing the factory single-layer 85 micron inlet screen with a two-layer 10 micron screen mounted on a stainless steel frame, this pump ensures uninterrupted fuel flow even in the face of debris accumulation. The increased protection provided by the finer screen not only enhances pump longevity but also boosts injector survivability by more than 85% compared to systems using the factory screen.

Exergy's commitment to quality and performance shines through in every aspect of this pump, offering customers unmatched peace of mind when it comes to their fuel system. With no core charge or return needed, the EXERGY E04 10504 pump is a hassle-free, cost-effective upgrade that will elevate the performance of your GM Duramax engine.

For optimal pump performance, a fuel supply of 150 GPH at 8-10 psi per pump is recommended, though a lift pump is not mandatory. Trust Exergy to deliver reliability and efficiency with the Improved Stock CP4.2 Pump, setting a new standard in fuel system excellence.
