Description
The FASS Drop-In Series fuel system replaces the factory filter assembly on 2019-2026 GMC/Chevrolet trucks with the Duramax 3.0L LM2/LZ0. It is not a lift pump: it works with your factory in-tank pump and adds FASS air/vapor separation, water separation and 2-micron filtration in the factory location.
Please note: Not compatible with the FASS Fuel Sump Kit. May not fit aftermarket high-capacity fuel tanks; verify clearance. Cab-and-chassis installs may require modification.
