Using the newest technology, Pureflow AirDog II-4G fuel air separation systems have been designed operate at flows and pressures beyond the maximum requirements of the engine. They will improve engine performance by maintaining correct injection timing, eliminating spray pattern disruption, and allowing for full power stroke and complete burn. The dual feed Gerotor pump and low-amperage motor provides efficiency and endurance, while the self-aligning motor design requires less maintenance and reduces noise levels. An intermediate pump shaft separates the motor from the fuel, and the compact design offers mounting versatility.
