RARAYC 6.7L Cummins Fuel & Water Separator Kit (2019-2024) — 3-piece set, 4-micron Ahlstrom media

RARAYC's 3-piece fuel filter and water separator kit replaces OEM 68157291AA, 68436631AA and 5083285AA to protect 6.7L Cummins Ram engines from water and particle contamination.

This replacement set combines two fuel/water separator elements and one oil filter engineered for 6.7L Turbo Diesel Cummins engines in 2019–2024 Ram 2500, 3500, 4500 and 5500 trucks. Built with Italy Ahlstrom three-layer synthetic filter media, the components capture water and particles down to four microns while maintaining flow for reliable start-up, injection protection and longer filter life between service intervals.

How does this kit reduce water and contaminant risk in my diesel system?

The dual-layer micro filter paper separates free water from diesel and traps particulate contaminants before they reach injectors and pumps. The outer layer knocks out bulk water while the inner synthetic layers capture fine particles, maintaining a steady, dry fuel supply to the engine.

• Removes up to 99% of free water and contaminants at 4 micron rating.
• Double-layer design for water-oil separation and fine particle capture.
• Higher dust-holding capacity than single-layer filters for extended service life.

Will these filters fit my Ram 6.7L Cummins from 2019 to 2024?

Yes — this RARAYC set is specified to replace part numbers 68157291AA, 68436631AA and 5083285AA and fits 2019–2024 Ram 2500, 3500, 4500 and 5500 trucks equipped with the 6.7L Cummins turbo diesel. Always verify your truck's OEM part numbers before installation.

• Direct replacement for OEM part numbers listed in the product title.
• Designed for 6.7L Cummins engines in Ram 2019–2024 heavy-duty models.
• Includes three filters and safety gloves for a complete service job.

How long will the filters last and how often should I change them?

Constructed from premium three-layer synthetic Ahlstrom media, the filters are engineered for extended life and higher dirt capacity. Typical recommended service intervals vary by usage and fuel quality, but these elements are rated to perform effectively across longer mileages than simpler single- or two-layer designs.

• Three-layer synthetic media extends lifespan to approximately 20,000–40,000 miles depending on conditions.
• Higher filtration efficiency at 4 microns versus common 5–10 micron options.
• Inspect filter condition and fuel system if you experience fuel delivery issues or contamination signs.

What comes in the package and is there support after purchase?

The kit ships with two fuel/water separator elements and one oil filter so you can complete a routine service, plus a pair of safety working gloves. RARAYC backs the kit with a 12-month warranty and lifetime support to help with replacements or fitment questions.

• Included: 1 x 68436631AA, 1 x 68157291AA, 1 x 5083285AA, and safety gloves.
• 12-month warranty and lifetime customer support from RARAYC.
• Clear OEM part number compatibility listed for verification before installation.

Who is this for: This replacement filter set is aimed at owners and fleet managers of 2019–2024 Ram heavy-duty trucks with the 6.7L Cummins turbodiesel who want OEM-fit filtration performance, improved water separation and longer filter life between services. It’s well suited for drivers operating on variable-quality diesel or in climates prone to condensation and water contamination, and for technicians seeking a direct-fit, higher-capacity filter solution backed by warranty support.
