RARAYC 6.7L Cummins Fuel Filter & Water Separator Set — Direct-Fit 2013–2018 Ram, NanoNet 3‑micron

High-efficiency RARAYC fuel filter and water separator set engineered to protect 6.7L Cummins engines in 2013–2018 Dodge Ram trucks by trapping contaminants and separating water before fuel reaches injectors.

Keep your diesel’s fuel system running clean and reliable with this upgraded replacement set. Designed as a direct-fit swap for the original assemblies, the kit pairs an advanced 3-micron NanoNet dual-mesh filter with a premium fuel filter element and a pair of safety gloves for installation. It replaces part numbers 68197867AA and 68157291AA and fits 6.7L Cummins engines in 2013–2018 Dodge Ram 2500, 3500, 4500 and 2015–2018 Ram 5500 trucks.

How does the NanoNet dual-mesh upgrade extend engine life?

The NanoNet 3-micron dual-mesh media captures finer particles than many standard filters, helping prevent abrasive contaminants from reaching high-pressure components. This reduces the chance of injector wear and helps maintain consistent fuel delivery under varied driving conditions.

• 3-micron NanoNet layer captures smaller debris before injectors.
• Dual-mesh design balances dirt-holding capacity with flow.
• Works in tandem with the fuel filter to trap larger particulates and separate water.

Will this kit fit my Dodge Ram and replace factory part numbers?

This set is formulated to be a direct replacement for the factory fuel-water separation system on the specified 6.7L Cummins platforms. It includes the upgraded element and a matching fuel filter so you can swap both components in one service.

• Fits 6.7L Cummins: 2013–2018 Ram 2500, 3500, 4500; 2015–2018 Ram 5500.
• Replaces OEM references: 68197867AA and 68157291AA (and equivalents).
• Pack includes one upgraded 68157291AA element, one 68065608AA fuel filter, and gloves.

How is water removed and why does that matter?

The assembly separates free water from diesel before the fuel reaches sensitive components. Removing water reduces corrosion risk and helps prevent poor combustion or sensor issues caused by contaminated fuel.

• Mechanical separation sheds free water into the bowl for manual drain.
• Filtration media captures emulsified contaminants and particulates.
• Regular replacement keeps separation efficiency high and protects downstream parts.

What should I expect during installation and maintenance?

Installation follows standard service procedures for in-line fuel/water separators and can generally be completed with basic hand tools. The kit ships with safety gloves and is made from high-quality materials intended for straightforward, professional or DIY replacement.

• Direct-fit design for easy swap—no major modifications required.
• Use gloves provided to keep components clean during changeover.
• Replace at manufacturer-recommended intervals or if contamination is evident.

Who is this for? If you own a Dodge Ram equipped with the 6.7L Cummins engine from the 2013–2018 model years and need to replace the fuel/water separator with an upgraded element, this RARAYC kit is a ready-to-install option. It suits fleet technicians, independent mechanics, and truck owners who want improved particulate capture and reliable water separation without altering factory plumbing. For buyers seeking better protection for injectors and fuel system components, this set offers an economical way to upgrade filtration performance with compatible, OEM-replacement form, fit, and function.
