ATRACYPART 6.7L Cummins Fuel Filter Water Separator Kit for 2019–2024 Ram 2500/3500/4500/5500 — Direct-Fit, O-Rings Included

ATRACYPART 6.7 Cummins fuel filter water separator kit is a direct-fit replacement that captures water and contaminants to protect the fuel system on 2019–2024 Dodge Ram 2500/3500/4500/5500 6.7L diesel engines.

This service kit replaces OEM numbers 68436631AA, 68157291AA (and related references) and includes the filter element and quality o-rings designed to restore proper filtration, reduce contamination-related wear, and maintain steady fuel flow. It’s built for heavy-duty diesel applications where trapping free water and particulates helps keep injectors, pumps, and sensors operating as intended. The assembly uses multilayer media and enhanced sealing to resist leaks and deliver long service life under typical driving and towing demands.

How does this filter protect my Dodge Ram’s fuel system?

The ATRACYPART water separator removes free water and filters fine particulates from diesel before they reach sensitive components. Cleaner fuel reduces abrasive wear and helps preserve pump and injector performance without altering factory fuel pressure or flow characteristics.

• Captures up to 98% of free water and contaminants.
• Multi-layer filter media for fine particle retention.
• OEM-style sealing surfaces and supplied rubber o-rings to prevent leaks.
• Direct-fit form and threads for straightforward installation.

How long will this replacement filter last and when should I change it?

Service life depends on driving conditions, fuel quality, and hours of operation; typical replacement intervals match manufacturer recommendations or whenever water collection signals require drainage. Inspect the separator during routine maintenance and swap the cartridge if you observe excessive contamination, degraded performance, or after the recommended mile/hour interval.

• Designed for extended durability under heavy-duty use.
• Change if you see water accumulation or fuel smell in the bowl.
• Follow vehicle manufacturer service interval or technician guidance.

Is this kit compatible with my truck and easy to install?

Will this filter affect engine performance or fuel economy?

Proper filtration helps maintain intended engine operation by delivering clean fuel at the correct flow rate; a clogged or degraded filter can reduce performance, while a fresh, correctly sized filter preserves normal power and efficiency. This ATRACYPART unit is made to match OEM flow characteristics so it won’t restrict fuel delivery when new and installed correctly.

• Engine performance preserved by preventing injector and pump fouling.
• Engine calibration and factory fuel pressure remain unchanged.
• Minimizes risk of service-related limp modes tied to fuel contamination.
