RARAYC NanoNet 3-Micron Fuel Filter Kit for 6.7L Cummins — Dual OEM Fit, Water-Repel Synthetic Media

RARAYC NanoNet 3-micron fuel filter kit replaces stock filters on 6.7L Cummins Rams (2019–2024) to trap finer particles and reduce water in the fuel system.

The RARAYC NanoNet kit contains two direct-fit fuel filters engineered to improve fuel cleanliness for Ram 2500, 3500, 4500 and 5500 trucks with the 6.7L Cummins turbo diesel. Designed as a drop-in replacement for part numbers 68436631AA and 68157291AA, the package also includes protective work gloves and a manufacturer-backed warranty. This product emphasizes a tighter 3-micron filtration rating and multilayer synthetic media to extend filter life and protect injection components without vehicle modification.

How does the NanoNet 3-micron filtration protect my Cummins engine?

The NanoNet filter media uses a dense, multi-layer synthetic fiber to intercept smaller particles and shed water more effectively than typical 4-micron elements. By capturing finer contaminants, it helps reduce wear on fuel pumps and injectors and maintains cleaner fuel delivery over longer intervals.

• 3-micron nominal filtration for finer contaminant capture
• Italy Ahlstrom synthetic fiber media designed to remove water and particulates
• Removes a high percentage of contaminants to protect injection systems

Will this kit fit my Ram 2500/3500 from recent model years?

The kit is specified to fit RAM trucks equipped with the 6.7L Cummins turbo diesel from model years 2019 through 2024, including 2500, 3500, 4500 and 5500 series. It replaces the OEM part numbers listed and installs without modifying factory components.
