FASS Fuel Systems Drop-In Series Diesel Fuel System for 2019-2024 RAM 6.7L Cummins - DIFSRAM4001

Fits: 2019-2024 RAM 2500 & RAM 3500 6.7L Cummins
Please Note: Installation of this kit on a cab and chassis may require modifications. Drop-In Fuel Systems are a plug-and-play filtration upgrade and are not compatible with our Fuel Sump Kit. No additional items are needed for installation. This plug-and-play filtration system retains the Cummins OEM in-tank fuel pump.
The FASS Drop-In Series Diesel Fuel System was engineered by FASS to be the most effective filtration solution for the 6.7L Cummins. Backed by our limited lifetime warranty, the Drop-In Series Fuel System protects your 6.7L Cummins 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% of the water from your diesel fuel, along with entrained air and debris down to 2 Microns, the Drop-In Series System protects the 6.7L Cummins’ injection system from premature failure.
Additionally, by eliminating the contaminants mentioned above, our Drop-In Series System for the 6.7L Cummins optimizes MPG (results will vary), restores horsepower, and sharpens throttle response.
And if reliability, optimized MPG, restored horsepower, and a sharper throttle response aren’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.
Our industry-leading water removal capabilities (3rd-party proven to exceed 99%) 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 filtration system. 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.
