RARAYC NanoNet 3-Micron Fuel Filter Kit for 6.7L Cummins Ram 2500/3500 — Dual‑Element Water‑Separating Upgrade

The RARAYC NanoNet 3-micron fuel filter kit replaces OEM units on 6.7L Cummins Ram trucks to deliver finer diesel filtration and longer service intervals.

Designed as a direct-fit upgrade for late-model Ram heavy-duty pickups, this two-filter kit swaps in the RARAYC NanoNet elements (part numbers 68436631AA and 68157291AA) to reduce contaminants and separate water more effectively than standard 4-micron filters. The package includes both filters plus a pair of safety gloves and is backed by a 12-month warranty and lifetime support.

How does the NanoNet 3-micron filter improve fuel cleanliness?

The NanoNet media uses a dual mesh, three-layer synthetic design that captures smaller particles and sheds water better than conventional paper filters. That finer filtration helps protect high-pressure fuel systems by removing debris and emulsified water before it reaches injectors and pumps.

• 3-micron filtration rating for finer particle capture
• Italy Ahlstrom synthetic fiber media for improved water separation
• Dual mesh structure for staged contaminant removal
• Removes up to 99% of water and contaminants at 4 microns performance benchmark

Will this kit fit my Ram 2500 or 3500 model?

This RARAYC kit is made to fit 6.7L Cummins-equipped Rams from model years 2019 through 2024, including 2500, 3500, 4500, and 5500 variants where those factory filter part numbers are used. It is a direct-replacement set for the corresponding OEM filter housings and mounting locations.

• Compatible with 2019–2024 Ram 2500 and 3500 heavy-duty trucks
• Also fits 4500 and 5500 models with 6.7L Cummins engines
• Includes both OEM-equivalent part numbers for straightforward swap
• Direct-fit design—no modifications required

How long can I expect these filters to last and what maintenance is recommended?

The NanoNet elements are engineered for extended service life, typically covering 20,000–40,000 miles depending on operating conditions and fuel quality. Regular inspections and following manufacturer service intervals will keep the fuel system protected and maintain performance.

• Service life: generally 20,000–40,000 miles under typical conditions
• Inspect fuel filters at routine service intervals or when fuel symptoms appear
• Replace both primary and secondary elements together for balanced protection
• Use included gloves when changing filters to avoid contamination

Who is this for: The RARAYC NanoNet 3-micron fuel filter kit is aimed at Ram owners and fleet operators with 6.7L Cummins engines who want a higher level of filtration than factory 4-micron elements. It's well suited for drivers dealing with variable fuel quality, frequent towing or heavy loads, or anyone seeking longer intervals between filter changes while maintaining OEM-fit convenience and warranty-backed support.
