The GMC Sierra 3500HD Diesel Fuel Injector Pump by Fleece Performance, known as the Modified CP3K, is engineered to enhance your vehicle's performance, specifically for the '01-'13 models. This premium injector pump is designed to optimize your fuel system's efficiency, ensuring you get the most horsepower possible.

The Fleece Performance Modified CP3K is crafted using the Duramax LBZ CP3 foundation, specifically designed to eliminate the factory-related fuel flow restriction that becomes evident at 3,000 RPM. This restriction can lead to a notable loss of horsepower, particularly when it is most needed. By integrating this pump, you'll experience enhanced fuel flow and consistent rail pressure beyond the 3,000 RPM threshold, allowing your GMC Sierra 3500HD to perform at its best.

Features

• Eliminates factory fuel flow restriction starting at 3,000 RPM.

• Cost-effective upgrade for enhanced power and efficiency.
• Tested on in-house engine simulator and pump test stand.
