Description: This DFD - 4000 Fuel Filter Delete Kit is a must - have for 2001 - 2016 GM vehicles with a 6.6L Duramax engine and a FASS Fuel Pump installed. Once you've set up an aftermarket fuel filtration system like our FASS Titanium Signature Series on your Duramax, you can ditch the factory fuel filter. It's no longer needed, but you still have to replace it every 5,000 - 8,000 miles as it's placed after our filtration system. The DFD - 4000 replaces the useless factory filter with a spin - on canister, letting fuel flow freely into the engine and saving you money. It's a great addition to your FASS Titanium diesel fuel pump and comes with all the necessary hardware for a professional installation. Features include eliminating the factory fuel filter, saving on replacement filters, free - flowing design, a fuel pressure port, no need for modifications, and easy installation. Note: This item is only for use with aftermarket filtration systems.
