FASS Fuel Systems Drop-In Series Diesel Fuel System 2017-2023 GM (DIFSL5P1001)

• Fits: 2017-2019 Crew Cab Short Bed L5P Duramax
• Fits: 2017-2023 Crew Cab Long Bed L5P Duramax

Part No: DIFSL5P1001 The FASS Drop-In Series Diesel Fuel System was engineered by FASS to be the most effective filtration solution for the L5P Duramax. Backed by our limited lifetime warranty, the Drop-In Series Fuel System protects your L5P Duramax from the issues caused by fuel contamination.

Without proper fuel filtration, modern diesel injection systems are prone to excessive wear, which can cost THOUSANDS! By removing over 99 percent of the water from your diesel fuel, along with entrained air and debris down to 2 Microns, the Drop-In Series System protects the L5P's injection system from premature failure. A

dditionally, by eliminating the contaminants mentioned above, our Drop-In Series System for the L5P Duramax optimizes MPG (results will vary), restores horsepower, and sharpens throttle response.

And if reliability, optimized MPG, restored horsepower, and a sharper throttle response isn't enough, this system can be installed in an hour or less! This is a true plug-and-play system, requiring no cutting, wiring, or additional modifications.

Better still, this system requires ZERO tuning changes! Whether your L5P is stock or modified, our Drop-In Series Systems will not require adjusting tunes or clearing any codes. Our industry-leading water removal capabilities (3rd-party proven to exceed 99 percent) are reinforced by the unique design of our Extreme Water Separator (XWS).

If our XWS reaches capacity, it acts as a dam, shutting down your truck and preventing major destruction of fuel system components.

FASS Drop-In Technology was developed to achieve industry-leading filtration with the simplest possible installation-making our Drop-In Series Systems a true bolt-in upgrade. If you're mechanically inclined, a Drop-In Series Fuel System can be installed in your driveway in less than an hour!

But don't let the easy installation fool you-our Drop-In Series Fuel Systems offer the same world-class filtration as our Titanium Signature Series and Industrial Series lines.

Performance Radius Cuts (PRC) are an advanced machining technique used to improve the flow of fuel through the FASS System by creating smooth-flowing cuts within the aluminum housing.

This prevents the reintroduction of air and vapor back into the fuel and prevents eddy currents from forming within the corner of a 90-degree sharp angle. FASS Drop-In Fuel Systems 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.
