2001-2004 Duramax Dual CP3 Kit w/Pump (DCP3CLB7)

Industrial Injection dual CP3 install kit with second CP3 pump included, for 2001-2004 Chevrolet Silverado 2500HD/3500 and GMC Sierra 2500HD/3500 6.6L LB7 Duramax. Available with the Dueling Dragons option (two 85% Dragon Fire CP3s) or the Dueling Double Dragons option (two 120% CP3s) for top-tier competition fuel supply.

A dual-CP3 setup adds a second CP3 pump driven off accessory power, sharing the fuel-delivery load with the original engine-driven CP3. Efficiency goes up, EGTs go down, and rail pressure stays constant under heavy demand. Each pump does half the work, which means the original internal CP3's drive load drops by 50% — better pump life. If one pump fails, the IIS controller automatically switches full delivery control to the remaining functioning pump.
