98.5-04 Dodge 5.9L Cummins AirDog 2 DF-175-5G Air/Fuel Seperation System

The AirDog II-5G A7SABD525 DF-165-5G Air/Fuel Separation System is a state-of-the-art fuel delivery system for your 1998.5-2004 Dodge 5.9 24V Diesel (Moderate to Extreme).

The AirDog II-5G offers protection and performance unlike any other lift pump. Their patented air separation, along with a water separator, and fuel filter makes sure your expensive fuel injection system components get all the clean fuel they can handle.  This helps overcome any loss of power due to driving in higher altitudes wish 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.

This wiring harness has been upgraded to 12-gauge from the battery all the way to the internal connections in the motor.  A Metri-Pack 280 connector replaces the Deutch 20pin connector which allows more current flow without creating excessive heat.  To help keep the elements out, all other connectors in the harness utilize weather packs.
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 features 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.
