The FASS DIFSL5P1001 Drop-In Series Fuel system that will improve the fuel system for your 2017-2019 6.6L Duramax L5P (Crew Cab, Short Bed) or 2017-2023 6.6L Duramax L5P (Crew cab, Long Bed). This fuel system was engineered by FASS to be the most effective filtration solution for your truck. Backed by a limited lifetime warranty, this fuel system protects the L5P Duramax from the issues caused by fuel contamination.
Due to the quality of diesel fuel available, modern diesel injection systems are prone to excessive wear without proper fuel filtration, which can cost thousands in repairs. This fuel system protects L5P's injection system from premature failure by removing over 99% of the water from your diesel fuel, along with entrapped air and debris down to 2 microns. Additionally, by removing the contaminats mentioned above, this fuel system helps optimize MPG (results will vary), restores lost horsepower, and sharpens trottle response.
If reliability, optimized MPG, restore horsepower, and sharper trottle response isn't enough, this system can generally be installed in an hour or less. This is a true plug-and-play system, with no cutting, wiring, or additional modifications required for installation. Better yet, this system requires no tuning changes. whether your L5P is stock or modified, this fuel system will not require adjusting tunes or clearing and check engine codes.
FASS industry-leading water removal capabilities have been 3rd-party proven to extend 99% and are reinforced by the unique design of the Extreme Water Separator (XWS) filter. When the XWS reaches capacity, it acts as a dam, shutting down the truck and preventing major damage to the fuel system components.
FASS Drop-In Technology
This fuel system was developed to achieve industry-leading filtration with the simplest possible installation, making FASS Drop-In Series System a true bolt-in upgrade.

Performance radius cuts (PRC)
An advanced machining technique used to improve the flow of fuel through the pump by creating smooth flowing cuts within the aluminum housing. This provents the introduction of air and vapor back into the fuel and also to provent stagnant fuel pockets from forming within the corner of a 90 degree bend. FASS Signature Series Fuel Pumps are the only Fuel Air Separation System that incorporates these exclusive Performance Radius Cuts, lesser competitors commonly use T-Bone and square 90 degree fittings that can limit fuel flow, cause restrictions and reintroduce air back into your fuel.
