LB7 Duramax New CP3 Pump – Dynomite Diesel NCP3-303

Restore reliable high-pressure fuel delivery to your 2001-2004 6.6L LB7 Duramax with the Dynomite Diesel NCP3-303 brand-new stock CP3 injection pump.

This is a direct-fit, brand-new OE Bosch-based CP3 pump built by Dynomite Diesel Performance (DDP). It is not a remanufactured unit. Each pump is assembled using a new Bosch core, includes a brand-new unmodified Fuel Control Actuator (FCA/regulator) for improved tunability, and is tested on DDP’s in-house engine simulator and test stand to ensure it meets or exceeds factory performance standards before it ships.

Key Features

• Brand-new (not reman) stock-output CP3 injection pump
• Direct replacement for the factory CP3 on 2001-2004 LB7 Duramax engines
• New unmodified FCA for better control and tunability
• No core charge
• Ready to install with no modifications required
• Maintains factory fuel volume and rail pressure for stock or mildly modified applications

Fitment

• 2001–2004 Chevrolet Silverado 2500HD / 3500HD

• 6.6L LB7 Duramax diesel

Why Choose the DDP NCP3-303?

A failing factory CP3 is a common weak point on early Duramax engines. Replacing it with a brand-new, properly tested unit from Dynomite Diesel eliminates the risk and uncertainty of a worn or contaminated reman pump while restoring proper rail pressure, throttle response, and overall drivability.

Warranty: 2-year unlimited mileage warranty from Dynomite Diesel.

Notes:

• For best results and longevity, ensure your fuel system is clean and that a quality lift pump is maintaining proper supply pressure.
