FLEECE FPE-DMAX-CP3K MODIFIED CP3 INJECTION PUMP-CP3K FOR 11-16 GM DURAMAX LML

The FLEECE FPE-DMAX-CP3K Modified CP3 Injection Pump is engineered to enhance the performance of your 2011-2016 GM Duramax LML. If you're looking to eliminate the factory fuel flow restriction that kicks in at 3,000 RPM, this modification is the solution you need. With a stock CP3 pump, you may experience a drop in fuel flow and rail pressure after 3,000 RPM, translating to a loss in horsepower precisely when you require it most. By opting for the CP3K upgrade, you can ensure consistent fuel rail pressure across your entire RPM range, unlocking the full potential of your vehicle's engine.

This impressive product from Fleece Performance comes equipped with a brand new Bosch CP3, ensuring top-notch quality and reliability. What's more, there is no core charge or core return required, making the upgrade process even more streamlined and hassle-free.

For those considering installing the FLEECE FPE-DMAX-CP3K in 2001-2005 (LB7 or LLY) vehicles, be aware that the fuel pressure regulator will need appropriate scaling. Detailed application notes and necessary values can be found on the Fleece Performance website.

With fitment options covering a wide range of GM Silverado/Sierra 2500/3500 models across various years, this modification is versatile and compatible with many Duramax engines. And to provide you with peace of mind, Fleece Performance offers a 1-year limited parts warranty, ensuring your investment is protected.
