Description 2001-2016 GM 6.6L Duramax Diesel Fuel Filter Delete Kit FASS DFD4000 FASS part number DFD4000 is a bowl that sits in place of the factory fuel filter on 2001-2016 Chevrolet & GMC trucks with the 6.6L Duramax diesel engine. When using another form of fuel filtration, such as the FASS Fuel Air Separation Systems, the factory fuel filter is no longer needed. This delete kit installs in place of the factory filter and keeps the water in fuel sensor and the factory fuel heater in place and operational. Performing fuel filter maintenance is made much easier! This kit must be used with a 10 micron or less fuel filter. We recommend a 2 or 3 micron fuel filter for maximum filtration. A port is included for fuel pressure sending units. If we do not have this part in stock, or it shows on back order, don’t worry. Huckstorf Diesel receives shipments from our suppliers daily.
