FASS Duramax Factory Fuel Filter Delete Kit, FASS Duramax Factory Fuel Filter Delete Kit
Once you’ve 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 pump and comes with all required hardware for a professional installation.

Other Popular Parts
FASS Fuel System (Fuel Air Separation System) is a combination diesel FASS fuel pump and fuel filtration system that is designed to improve your diesel trucks fuel mileage, engine performance and extend the life of your diesel injection system.
FASS fuel system manufactures from American made components that are then assembled and tested in house using the highest quality components. FASS Diesel systems fit most Ford Powerstroke, Dodge Cummins, and GM Duramax Engines.
With a FASS Fuel Pump or FASS fuel filters only the purest quality fuel is delivered to your diesel engine by removing dirt, water and air through a two step filtration process while switching the fuel delivery process from a suction delivery to a pressure delivery, eliminating the possibility of reintroducing air back into the fuel after it has already been removed. FASS Fuel Filters (diesel) have a rating as low as 3 Micron, which provides superior protection from debris in your diesel fuel and engine.
