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.
Note: *Does not work on 2014 Cummins with split radiator hose*
