Description
Product Overview
The Generic Lml‑CP3 Conversion Kit is engineered for 2011‑2016 Chevrolet Silverado and GMC Sierra 2500hd models with the 6.6L V8 Duramax diesel engine. Constructed from high‑grade alloy steel, aluminum and reinforced rubber, the kit includes a complete set of fuel lines, mounting brackets, clamps, fittings and all necessary hardware. Its direct bolt‑on design matches factory mounting locations, eliminating the need for custom fabrication. The kit operates in a direct high‑pressure fuel injection mode, ensuring precise fuel metering and consistent performance even under heavy load.
Usage
This conversion kit is ideal for owners seeking to replace a worn or failed CP3 pump, as well as for those upgrading to a more robust fuel delivery system for towing, off‑road adventures, or commercial use. Installation is performed at the front of the engine, directly bolting onto existing mounting points. While the kit is designed for a straightforward swap, professional installation is recommended to guarantee proper torque settings and fuel system integrity. Once installed, the truck benefits from smoother acceleration, reduced fuel pressure fluctuations, and enhanced overall durability.
