FASS Fuel Systems 2001-2016 Duramax Factory Fuel Filter Delete Canister (DFD4000) Part No: DFD4000 Once youve installed an aftermarket Fuel Filtration System such as our FASS Titanium Series, the use of the factory fuel filter is no longer required and can be removed. Because your Duramax factory fuel filter is located after our filtration System you will still need to replace the factory filter every 5,000-8,000 miles. This filter delete kit will replace your now useless fuel filter with a spin on canister that will allow fuel to flow freely into the engine, saving you even more money. This spin on Fuel Filter Delete Kit is a perfect addition to your FASS Titanium diesel fuel System and comes with all required hardware for a professional installation. Duramax Fuel Filter Delete Kit Features: Eliminates Your Factory Fuel Filter Saves Money on Replacement Filters Free Flowing Fuel Pressure Port No Modifications Required Note: This item is only to be used with an aftermarket filtration Systems. We suggest the use of our Titanium Series Systems.
