Exergy Performance LML Improved Stock CP4.2 Pump | 2011-2016 GM Duramax 6.6L

Are you loosing rail pressure from a worn out CP4.2 pump? Are you in need of a factory replacement pump? From stock up to 550+HP our Improved Stock LML CP4.2 pumps are the best and most affordable solution for an upgraded pump that won't require supporting modifications or tuning.

Our Improved Stock pump comes with our System Saver Inlet Metering Valve installed. This inlet valve replaces the factory single layer 85 micron inlet screen that is molded in a plastic frame with our two layer 10 micron screen which is mounted on a stainless steel frame that will not fail when the screen fills with debris and becomes a restriction. Not only is the screen over eight times finer than the factory screen, but the addition of another layer further increases protection from debris.

Based on a number of injector sets we have tested from systems with a failed pump with a System Saver installed it appears that injector survivability is increased more than 85% when compared to pump failures with the factory screen.

Let Exergy give you peace of mind with your fuel system purchase!

Note: Though a lift pump is not required, to achieve maximum pump performance a fuel supply of 150 GPH @ 8-10 psi per pump is recommended.

NO CORE CHARGE or CORE RETURNED NEEDED!!!
