The AirDog® II-5G is the first diesel Fuel Air Separation System to include an integrated diaphragm fuel pressure regulator. 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.
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 packs 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.
This Fuel System is designed to improve both reliability and performance by ensuring that there is always enough clean, air free fuel to keep up with the demands of the injection pump, often reducing wear/tear on the entire fuel system and resulting in a smoother running engine.
Pump Sizes/Recommendations:
Airdog 100GPH: Stock to 600+WHP
Airdog 165GPH: Stock to 900+WHP
Airdog 220GPH: Applications above 900+WHP
Important Note:
These systems are designed for trucks that have the factory lift pump on the driver side of the engine block, if your truck has the updated in-tank style pump (usually found in 04.5+) you will want to order the 05-18 kit.
