iFJF 68065612AA Fuel Filter Housing Cover Cap Replacement - Billet

Our review of the iFJF 68065612AA fuel filter housing cover cap finds it a practical, long-lasting upgrade for Ram and Dodge trucks with the 6.7L Cummins diesel. Designed as a direct replacement for the OEM cap, this CNC billeted aluminum cap is aimed at owners who want a more durable alternative to the stock plastic unit and a simple, tool-friendly service experience. The single biggest reason to buy is durability: the billet construction and precision machining reduce the risk of fuel leaks and avoid the rounded OEM profile that complicates removal.

Key Features

• Compatibility: Fits the fuel filter housing for 2011-2023 Ram 6.7L 2500, 3500, 4500, and 5500 and 2010 Dodge Ram models, so it replaces the OEM 68065612AA cap without modification.
• Material: CNC billeted aluminum construction provides greater durability and resistance to wear compared with the standard plastic cap.
• Installation: The flat-sided design accepts a 1 1/8' socket wrench for straightforward removal and reinstallation, speeding routine filter changes.
• Sealing: Precision machining improves sealing to help prevent fuel leaks and support reliable filtration system operation over time.
• Package: Includes the cap only, relying on the new filter's o ring so there is no duplicate seal in the box.

Who It's For

This cap is best for Ram and Dodge owners who perform their own maintenance and want a tougher, serviceable alternative to the fragile OEM plastic cap. It appeals to users who value a clean installation, a tool-accessible shape, and reduced chance of cap failure or leakage during heavy use.

It is not for buyers who expect additional seals or a full accessory kit in the box since the package contains the cap only and assumes the filter provides the o ring. Also, those who prioritize cosmetic perfection should inspect for potential cosmetic marks in the threads, as some customers reported surface imperfections.
