RARAYC 6.7L Cummins Fuel Filter Water Separator Set — 3‑micron NanoNet + OEM Primary for 2013–2018 Ram 2500–5500

The RARAYC Upgrade Fuel Filter Water Separator Set is a direct-fit replacement for 6.7L Cummins Dodge Ram models (2013–2018) that combines a 3-micron NanoNet dual-mesh element with a high-efficiency primary filter to block water and contaminants before they reach the engine.

If you own a 6.7L Cummins-powered Ram 2500, 3500, 4500 or 5500 (model years 2013–2018), this kit replaces factory part numbers 68197867AA and 68157291AA and is designed to improve fuel cleanliness and protect fuel-system components. The set includes an upgraded 3-micron NanoNet filter (part 68157291AA upgrade), an OEM-style 68065608AA fuel filter, and a pair of safety gloves for installation. Built from premium media, the filter combination captures fine particulates and helps separate water from diesel to reduce injector fouling and maintain consistent fuel-flow performance.

How does this upgrade differ from the stock fuel filter?

The RARAYC set adds a 3-micron NanoNet dual-mesh element alongside the standard filter to trap smaller particles and enhance water separation compared with typical OEM-only elements. Materials are selected to increase filtration efficiency while maintaining required flow rates for the 6.7L Cummins fuel system. Installation follows the same service procedures as the factory unit, so no special tools or modifications are required.

• Includes NanoNet 3-micron dual-mesh plus OEM-style primary filter
• Higher micron-capture performance versus many stock elements
• Direct-fit replacements for factory part numbers listed
• Includes gloves for safer filter handling during service

Will this set remove water and protect my injectors?

The combination of the upgraded element and the primary filter improves water separation and particle capture to help reduce the chance of contaminants reaching injectors. While no filter can guarantee complete prevention of injector issues, this set reduces common contaminants that contribute to wear and clogging. Regular replacement following service intervals is still important for ongoing protection.

• Enhanced water separation with dual-mesh media
• Captures 99.9% of particles 5 microns and larger (premium material)
• Helps reduce injector exposure to debris and emulsified water
• Recommended replacement aligns with manufacturer service intervals

Is the RARAYC set easy to install and compatible with my truck?

The set is engineered as a direct-replacement for the 6.7L Cummins fuel filter housing on Dodge Ram 2500, 3500, 4500 (2013–2018) and Ram 5500 (2015–2018). Installation uses the same mounting points and seals as the original equipment, so a routine filter service procedure applies. If you can perform a standard fuel filter change, this kit fits into that workflow with the included gloves for cleaner handling.

• Direct-fit for the specified model years and engines
• No housing modifications or special adapters required
• Includes protective gloves for a neater installation
• Professional-grade material but home-install friendly

What does the kit include and what factory numbers does it replace?

The kit ships with the upgraded NanoNet 3-micron filter (68157291AA upgrade), one OEM-style 68065608AA fuel filter, and a pair of safety working gloves. It is intended to replace factory references such as 68197867AA and 68157291AA, matching the fit and sealing surfaces required by the original fuel filter assembly. RARAYC backs the set with a one-year satisfaction guarantee and offers customer support if any issues arise.

• 1 x 68065608AA OEM-style fuel filter
• Pair of safety working gloves included
• One-year guarantee with direct seller support

Who this is for: drivers and technicians who maintain 6.7L Cummins Ram trucks from 2013–2018 and want an upgraded filter solution that improves fine-particle capture and water separation while remaining a direct, bolt-in replacement for the factory unit. It’s suitable for fleet maintenance, DIY service enthusiasts, and anyone looking to add extra protection to the fuel system without changing OEM service procedures.
