The New Industrial Injection Dual CP3 is the ultimate in performance. Efficiency is increased and EGT's reduced while providing enough fuel to make over 1200HP.

 Both pumps work together by delivering half the total volume of fuel required. Since each pump now shares the total fuel delivery, drive load on the original internal cp3 pump is reduced by 50%. This not only increases reliability but also reduces wear and tear. The dual CP3 kit provides a seamless and consistent fuel flow for large injectiors and aggressive programming that demands a high volume of fuel and optimal fuel rail pressure. As an added benefit, in the event of pump failure Industrial Injection's controller will automatically switch full fuel delivery control to the remaining functioning pump.
