Maximum Protection & Performance for Your Cummins

The AirDog II-5G 165GPH Lift Pump is a premium diesel fuel-air separation system designed specifically for 2019–2023 RAM 2500 and 3500 trucks equipped with the 6.7L Cummins engine. Diesel fuel often contains contaminants like dirt, rust, and water that can damage your fuel injection system and engine components. This lift pump effectively removes those impurities, delivering clean diesel fuel to your engine for better reliability and enhanced performance.

Boost Fuel Efficiency and Power

By filtering out particulates and separating air/vapor from the fuel, the II-5G ensures optimal fuel atomization at the injector. This not only increases fuel economy but also improves throttle response, horsepower, and torque. The diaphragm-regulated design maintains stable fuel pressure, protecting high-precision injection systems from pressure drops that can cause damage or inefficiency.

Quiet, Reliable, and Built to Last

AirDog has engineered the II-5G system around their proven 4G motor technology, delivering whisper-quiet operation and exceptional reliability. The system’s demand flow design returns unused fuel back through the filter, constantly circulating clean diesel to prevent stagnation and ensure peak performance. The included complete installation kit simplifies setup, reducing installation time and effort.
