This complete fuel delivery system increases fuel volume and quality, ensuring your CP4 injection pump receives clean, properly pressurized fuel for improved performance, throttle response, and overall engine reliability. By removing entrained air and contaminants and providing a consistent fuel supply, the AirDog II-5G helps reduce the risk of cavitation and premature wear on the injection system.

The integrated diaphragm fuel pressure regulator comes preset at 8-10 psi and supports efficient fuel delivery without overtaxing the stock CP4 pump.
