2004 - 2005 Duramax LLY Dual Cp3 Kit (W/O Pump)

The Industrial Injection dual CP3 is the ultimate for performance. This kit can be purchased with a new, modified, Dueling Dragons (two 85% Dragon Fire CP3s) or the Dueling Double Dragons (two 120% CP3s) CP3's for those who compete in the competition circuits.

Efficiency is increased and EGTs reduced (constant optimum fuel pressure is maintained). Both pumps work together, each delivering half the total volume of fuel required, effectively sharing the fuel delivery load. Since each pump now shares the total fuel delivery, the drive load on the original internal CP3 pump is reduced by 50% increasing pump reliability. As an added benefit in the event of a pump failure, Industrial Injection's controller will automatically switch full fuel delivery control to the remaining functioning pump.
