Exergy Performance 2011-2016 LML Duramax Improved Stock CP4.2 Pump with upgraded heavy duty FPRV Screen
This Improved Stock pump comes with a 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.
There are further improvements beyond the fuel system saver:
- Pump followers are now pinned which prevents the buckets from rotating, causing the roller to grind along the cam.
- Rollers now have an increased diameter which makes them less susceptible to contamination jamming the roller. It also lowers the stresses at the cam/roller interface.
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.
This pump can be used as a direct replacement for Bosch part numbers 0 445 010 616, 0 986 437 421, and 0 445 010 817, as well as GM part numbers 98077841, 12645102, 12638262, 12658095, and 12661059.
