Key Features

• Complete Dual-Stage Filtration – Combines a high-efficiency fuel filter and water separator in one reliable set, removing solid particles and separating water from diesel fuel before it reaches the engine. This two-stage process is essential for protecting modern high-pressure common rail fuel systems, where even microscopic debris or water droplets can cause injector damage or reduced combustion efficiency.
• Precise OEM Fit – Manufactured to exact specifications for 2019–2024 Dodge Ram 2500, 3500, 4500, and 5500 trucks with 6.7L Cummins turbo diesel engines, ensuring hassle-free installation and leak-free operation. The components match original equipment dimensions, sealing surfaces, and mounting configurations, so you can replace your old filters with confidence and minimal downtime.
• Broad Part Number Compatibility – Replaces multiple OE and aftermarket numbers including 68157291AA, 68436631AA, 68065608AA, 680616344AA, MO608, DF99085, WF10112, FF1279, BF46031, MO867, L6806F, 33255, DF401-AD, WF10255NP, FF1199, PF9870, FS53000, PTC 43GF, EX43, and PF46152. This wide interchangeability makes it easier to source the correct replacement without relying on dealership parts.
• Premium Construction – Built with durable, high-quality materials tested to meet or exceed OEM performance standards, offering long service life and consistent filtration under demanding conditions. The filter media is designed to maintain flow rates and capture efficiency across a full service interval, even in extreme temperatures or high-mileage applications.
• Cost-Effective Alternative – Delivers the same level of protection as dealership parts at a significantly lower price, helping owners reduce maintenance costs without sacrificing quality. With a price that’s only a small fraction of what dealerships charge, this set makes regular maintenance more affordable for both individual owners and fleet managers.

Benefits & Use Cases

This fuel filter and water separator set is essential for maintaining peak performance in modern diesel engines, where even microscopic contaminants can damage injectors and reduce fuel efficiency. By effectively capturing dirt, rust, and other particulates while separating water from diesel fuel, it prevents corrosion and fuel system damage—especially critical in humid or cold climates where condensation is common. Water in diesel fuel can lead to microbial growth, injector corrosion, and poor combustion, all of which this dual-stage system helps eliminate.

Regular replacement with this high-quality set is recommended during scheduled maintenance intervals to ensure optimal combustion and engine reliability. Diesel engines rely on precise fuel delivery, and contaminated fuel can disrupt injector timing, reduce power output, and increase emissions. This filter set helps maintain factory performance by keeping the fuel clean and dry from tank to injector.

It’s particularly valuable for fleet operators, commercial drivers, and off-road users who depend on their Ram trucks for heavy-duty tasks. Whether you’re hauling equipment, towing trailers, or driving in remote areas with limited access to premium fuel, this filtration system adds a layer of protection against inconsistent fuel quality. The direct-fit design allows for quick and easy installation, minimizing vehicle downtime and getting you back on the road faster.

Important Notes

This filter set is designed exclusively for 2019–2024 Dodge Ram 2500, 3500, 4500, and 5500 models with 6.7L Cummins turbo diesel engines. Verify your vehicle’s model year, engine size, and configuration before purchase to ensure compatibility. Always follow the manufacturer’s recommended replacement schedule and torque specifications during installation. While this product is built to meet or exceed OEM standards, improper installation or use in incompatible vehicles may result in performance issues. The included 6-month warranty covers defects in materials and workmanship under normal use conditions. For best results, replace both filters together as a set to maintain balanced system performance.
