2019-2026 3.0L Duramax Drop-In Fuel System Adapter Kit (LZ0ADPT1001)

Description This is the application adapter kit that lets the FASS Drop-In Series Fuel System be installed on the 3.0L Duramax. FASS builds one Drop-In housing for the Duramax platform and pairs it with a vehicle-specific adapter kit, so the adapter is what makes the system bolt into a 1500-series truck or SUV rather than a 6.6L HD truck. Choose 1500 Truck for Silverado 1500 and Sierra 1500 pickups in any cab and box configuration, or 1500 SUV for Tahoe, Suburban, Yukon, Yukon XL, Escalade and Escalade ESV. The Drop-In Series itself is an air separation and filtration system, not a lift pump. It replaces the plastic OEM single filter housing with a CNC machined 6061-T6 billet aluminum dual filter housing, retains the factory in-tank lift pump, and keeps the OEM water separator element so the water-in-fuel sensor continues to warn you before water reaches the clean side of the filter. *This adapter kit is not a complete fuel system on its own. It must be installed together with the FASS Drop-In Series Fuel System (DIFSL5P2001), which is sold separately.
