Description

The FASS DFD-4000 Duramax Fuel Filter Delete for your 2001-2016 GM 6.6L Duramax is for use after the installation of a FASS Fuel Air Separation System. Once installed the factory fuel filter is no longer needed and can be easily removed by using this Factory Fuel Filter Canister Delete. Because your Duramax fuel filter is located after the FASS 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 pump and comes with all required hardware for a professional installation.

Features:
  • Installs In Place Of Stock Filter 
  • Allows For Unrestricted Fuel Flow To Engine 
  • Built-In Gauge Port For Fuel Pressure Monitoring
  • Eliminates Costs Associated With Changing Stock Filter
Note: This product is ONLY for use on trucks that already have another form of filtration such as a FASS Titanium Series Fuel System.

Works like it should, BUT there parts you need to remove from the factory filter mount before it will work. Wish it came with instructions but FASS has a video on their youtube. Order 2038927
