Diesly PRO Fuel Filters are purpose-built for Cummins diesel owners who demand more than basic filtration. Designed specifically for the 2019-2024 Ram 2500, 3500, 4500, and 5500 models equipped with the 6.7L Cummins Turbo Diesel, this complete two-filter kit includes the engine-mounted fuel filter and the frame-mounted water separator, both rated at 3 microns to meet OEM standards. What sets Diesly PRO apart is more than performance-its protection. We back our filters with the industry's first Lifetime Injector Warranty, offering fuel system coverage when used with proper maintenance. Registration is required within 30 days of purchase and conditions apply (see insert or visit DiYparts.com/Diesly). Each filter in the PRO series is built with high-capacity pleated media and designed for easy drop-in installation. The included O-rings and OE design ensure a secure fit with zero guesswork. Whether you're replacing OEM part numbers like 68436631AA or 68157291AA, or equivalent parts from Baldwin, Fleetguard, or WIX, Diesly PRO delivers uncompromising compatibility. With a recommended service interval of every 15,000 miles or 12 months, our filters help maintain injector life, power output, and engine reliability. Proudly shipped from our Greensboro, NC warehouse, we do not dropship-our parts, our inventory, our team. Clean fuel isnt optional. Its essential. And with Diesly PRO, it's protected. Note: Registration required for injector warranty. Always consult your vehicles owner manual for maintenance intervals.
