FASS 19-23 6.7L Cummins Drop-In Series Fuel System

The FASS Drop-In Series Diesel Fuel System is designed to revolutionize fuel filtration for 2019-2024 Ram 6.7L Cummins engines. It boasts a 99% efficiency rating in filtering out water, air, and debris, preventing particles down to 2 microns from entering the fuel system. This protection helps prevent premature engine failure, even during high-performance driving. By eliminating contaminants, the system optimizes MPG, restores horsepower, and sharpens throttle response. It is the only filtration system on the market that retains full functionality of the water-in-fuel sensor and separates entrained air.
