Adding a belt driven CP3 Pump Kit to your stock fuel system reduces drive load on the internal gear driven CP3 pump, increasing pump reliability. Both pumps work together, each delivering half the total volume of fuel required, effectively sharing the fuel delivery load. In the event of a pump failure, PPE’s electronic controller will automatically switch full fuel delivery to the other remaining functional pump. The Dual Fueler Kit will not produce more fuel pressure than the ECU requests, it will only increase fuel volume. If the tuning is modified, or a Duramaximizer is also used, the fuel pressure can be increased over factory pressure resulting in additional horsepower and torque. The Dual Fueler Kit provides seamless and consistent fuel flow for large injectors and high level tune programs that demand a high volume of fuel and optimal fuel pressure at the injectors. The size of the PPE pully is determined so the second belt driven PPE pump runs at the same exact speed as the factory gear driven pump to eliminate high rpm cavitation, and have uniform flow output from each pump. Supports race modified installations that will produce up to 1200 HP and 28,000+ PSI!
