This regulator allows for more fuel pressure adjustability, offers better fuel flow at pressure, and can be boost compensated! This system has larger porting to allow less cavitation and noise at the inlet of the higher flowing 220GPH pumps. All AirDog II-5G systems come with improved wiring harnesses and connectors as well! The wiring harness is now 12ga from the battery all the way to the internal connections in the motor. A Metri-Pack 280 connector replaces the Deutch 2 pin connector which allows more more current flow without creating excessive heat. All other connectors in the harness are weather pack to keep the elements out. This system has the same 4G motor technology that has proven itself to be a reliable, quiet operating system. It also retains the “Demand Flow” of the older AirDog II variants. Demand Flow means whatever fuel the injection system does not consume gets recirculated back through the filter base.
