6.7 Cummins Fuel Filter Water Separator Set - OEM Fit Replacement

In this review of the 6.7 Cummins Fuel Filter Water Separator Set the bottom line is simple: this kit is a practical, cost effective replacement for owners of 2019-2024 Ram 2500, 3500, 4500 and 5500 trucks with the 6.7L turbo diesel who need a direct-fit fuel filter and water separator. The reviewer found it delivers the core function of protecting the fuel system from contaminants and water, installs easily, and mirrors OEM fit and function, making it a straightforward maintenance choice for routine service intervals.

Key Features

• Direct replacement: Designed to replace factory parts including 68157291AA and 68436631AA so it fits the intended Ram models without modification.
• Fuel system protection: The set removes particles and separates water to reduce contamination risk and help extend engine life.
• Wide compatibility: Specified for 2019-2024 Ram 2500, 3500, 4500 and 5500 with the 6.7L turbo diesel, making it suitable for a large group of owners.
• Durable construction: Made from materials tested to meet or exceed OEM standards, offering confidence in basic longevity under normal conditions.
• Backed warranty: Includes a 6 month warranty and a return policy that provides some protection after purchase.

Who It's For

This set is best for owners and DIY mechanics who need an affordable, OEM-fit fuel filter and water separator for regular maintenance on 6.7L Cummins powered Rams from 2019 through 2024. It is especially useful for fleet trucks and heavy users who value a correct fit and straightforward swap at a lower price than dealer parts.

It is not the right choice for someone who requires extended aftermarket warranties, dealer-origin packaging, or who is unwilling to accept the occasional report of internal filter failure; buyers with those priorities should consider factory-sourced parts or higher-tier aftermarket options.

Pros & Cons

Pros

• Good OEM-style fit and compatibility for specified Ram models, so installation is typically problem free.
• Effectively separates water and traps particles, improving fuel system protection when installed correctly.
• Strong value for the price compared with dealer parts, making routine service less expensive.

Cons

• Some customers reported build quality issues where elements of the filter separated inside the housing, so occasional quality variation exists.
• Warranty is limited to six months, shorter than some extended aftermarket or dealer warranties.
