Drop-In Fuel Systems are a plug-and-play filtration upgrade and\u003cstrong\u003e\u003cem\u003e are not compatible\u003c\/em\u003e\u003c\/strong\u003e with our Fuel Sump Kit. No additional items are needed for installation. This plug-and-play filtration system retains the OEM in-tank fuel pump. This kit is designed for both crew cab short and long bed trucks. \u003cstrong\u003eThe Drop-In Series for the L5P Duramax may not work with aftermarket oversized fuel tanks due to mounting space restrictions.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eWithout 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 L5P’s injection system from premature failure.\u003c\/p\u003e\u003cp\u003eAdditionally, 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.\u003c\/p\u003e\u003cp\u003eAnd if reliability, optimized MPG, restored horsepower, and a sharper throttle response isn’t enough, \u003cstrong\u003e\u003cem\u003ethis system can be installed in an hour or less\u003c\/em\u003e\u003c\/strong\u003e! 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.\u003c\/p\u003e\u003cp\u003eOur 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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\u003cbr\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFASS Drop-In Technology\u003c\/strong\u003e 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.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePerformance Radius Cuts (PRC)\u003c\/strong\u003e 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.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":50168646107375,"sku":"DIFSL5P2001","price":684.97,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/6397\/9503\/files\/Screenshot_27-7-2026_95843_www.fassride.com.jpg?v=1785160733","url":"https:\/\/www.screamindieselstore.com\/products\/fass-drop-in-series-diesel-fuel-system-for-gm-chevrolet-2020-2025-duramax-6-6l","provider":"Screamin' Diesel Store","version":"1.0","type":"link"}
