FASS Drop-In Series

The FASS Drop-In Series Diesel Fuel System was engineered by FASS to be the most effective filtration solution for the Cummins. Backed by their FASS limited lifetime warranty, the Drop-In Series Fuel System protects your Cummins from the issues caused by fuel contamination.

Without proper fuel filtration, modern diesel injection systems are prone to excessive wear, which can cost THOUSANDS! By removing over 99% of the water from your diesel fuel, along with entrained air and debris down to 2 Microns, the Drop-In Series System protects the Cummins injection system from premature failure.

NOTE: This is a filtration system only and requires the OE in-tank lift pump to operate.
