The AirDog II-5G A7SPBD253 DF-100-5G Air/Fuel Separation System from XDP is the latest and greatest in fuel delivery for your 1998.5-2004 Dodge 5.9L 24V Diesel (Stock To Moderate) (Without In-Tank Fuel Pump).

The AirDog II-5G is the first diesel Fuel Air Separation System to include an integrated diaphragm fuel pressure regulator. This regulator offers better fuel flow at pressure, allows for more fuel pressure adjustability, and can even be boost compensated. In addition, all 5G systems come with upgraded wiring harnesses and connectors.

The AirDog II-5G offers protection and performance like no other lift pump. Their patented air separation, along with a water separator, and fuel filter makes sure your expensive injection system components get all the clean fuel they can handle. The AirDog II-5G also overcomes loss of power due to driving in higher altitudes with a factory fuel pump. This system improves engine performance by eliminating spray pattern disruption due to air entering the system. This allows the engine to keep its designed injection timing which allows a more complete burn of the fuel entering the cylinder. This increases overall engine efficiency across the power and torque range.

The wiring harness is now 12-gauge 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 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 use gets recirculated back through the filter base.
