PureFlow AirDog II-5G DF-165-5G Fuel Air Separation System for 1989-1993 Dodge Ram 5.9L 12V Cummins
1989-1993 Dodge Ram with the 5.9L 12V Cummins PureFlow AirDog II-5G DF-165-5G system. This diesel lift pump delivers 165 gallons per hour of clean, air-free fuel directly to your injection pump, ensuring consistent power delivery even under heavy loads or modifications. By separating air and vapor from the fuel before it reaches the engine, it reduces injector wear, boosts throttle response, and maintains steady pressure across the RPM range—addressing common issues like fuel starvation that plague stock systems and lesser aftermarket pumps. Drivers report smoother operation and fewer breakdowns compared to mechanical pumps that struggle with viscosity changes or electrical lift pumps that fail to eliminate contaminants effectively.
This system stands out for 12V Cummins owners seeking reliable performance without the noise or complexity of competitors. Its demand flow design returns excess fuel to the tank at low pressure, minimizing aeration and heat buildup, while the integrated water separator catches moisture before it damages components. For trucks running stock tunes or moderate upgrades like larger injectors and turbos, this setup provides the fuel volume needed for peak efficiency, making it the practical pick for daily drivers and weekend haulers alike.
