Engineered specifically for high-horsepower competition and towing 2006 through 2010 Chevrolet Silverado and GMC Sierra 2500HD/3500 trucks powered by the 6.6L Duramax V8 turbo diesel engine (LBZ and LMM codes), the Industrial Injection Dual CP3 Pump Installation Kit (Part # 438402 — supplied without secondary pump) supplies the essential hardware framework required to add a secondary high-pressure fuel pump.

Aggressive custom tuning and oversized turbochargers demand fuel volumes that stock single-pump configurations cannot sustain under heavy load. This Industrial Injection kit provides the structural brackets, high-pressure lines, fittings, and drive hardware necessary to mount a secondary CP3 pump, increasing total system efficiency, maintaining stable rail pressure, and significantly lowering exhaust gas temperatures (EGTs) with zero core charge.

Key Features & Benefits

• Supports Extreme Horsepower Builds: Engineered to accommodate dual high-pressure CP3 pumps for high-output towing and competition applications.
• Reduces Exhaust Gas Temperatures (EGTs): Maintains constant, optimum fuel rail pressure under wide-open throttle to improve combustion efficiency.
• Complete Hardware Framework: Includes precision-machined mounting brackets, drive belts, high-pressure hard lines, and fittings (secondary pump sold separately).
• Robust Industrial Durability: Built from heavy-duty materials designed to withstand severe under-hood vibration and high torsional pressure loads.
• Zero Core Charge: Outright performance hardware kit requiring no core deposit or core return shipping.
