RARAYC NanoNet 3-Micron Fuel Filter Kit for Ram 2500/3500 6.7L Cummins — Dual 3‑micron Elements, Complete Two‑Filter Service Set

RARAYC NanoNet 3-micron fuel filter kit replaces factory elements in 2019–2024 Ram 2500/3500/4500/5500 6.7L Cummins trucks to provide finer diesel filtration and a complete two-filter service set.

If you service a late-model Ram with the 6.7L Cummins, this RARAYC NanoNet kit offers a direct-replacement fuel filter solution built around a finer 3-micron dual-mesh element and an included secondary cartridge. The kit arrives with both required filter housings (part numbers 68436631AA and 68157291AA) plus basic protective gloves, so you can complete the fuel-filter change with fewer trips to the parts counter. Materials and construction lean on premium Ahlstrom synthetic fiber media made in Italy, and RARAYC backs the kit with a 12-month warranty.

How is this NanoNet filter different from standard replacements?

The NanoNet uses a 3-micron dual-mesh design intended to trap smaller particles than common 4-micron filters, while the three-layer synthetic media improves water separation performance. It’s engineered to match the shape and sealing surfaces of the OE housings referenced, so installation follows the same routine as factory service items.

• 3-micron dual-mesh element for finer particulate retention compared to typical 4-micron filters.
• Three-layer Ahlstrom synthetic fiber media for enhanced contaminant and water handling.
• Includes both primary and secondary filter cartridges for a complete service change.

Will this kit fit my Ram 2500 or 3500 with a 6.7L Cummins?

Yes — the RARAYC kit is specified for 2019 through 2024 Ram 2500, 3500, 4500, and 5500 models equipped with the 6.7L Cummins turbo diesel. The pack contains the two filter part numbers commonly used on these model years so it replaces the factory pair without modification.

• Compatible model years: 2019, 2020, 2021, 2022, 2023, 2024.

How long can I expect the filter media to last before service?

Service life varies by fuel quality and operating conditions, but the RARAYC NanoNet media is designed for extended intervals similar to OE recommendations. Typical change intervals fall into a broad range based on manufacturer guidance and real-world use; inspect the system as recommended in your vehicle manual and replace both elements as a matched set.

• Media rated for long-life performance under normal operating conditions.
• Designed to handle extended intervals commonly recommended for modern diesel systems.
• Always follow vehicle manufacturer service intervals and inspection steps.

What comes in the kit and what else should I prepare for installation?
