iFJF Fuel Filter Housing Cap for Ram 6.7L Cummins — CNC Billet Aluminum, 68065612AA

This iFJF replacement cap is made to fit the fuel filter housing on Ram and Dodge trucks with the 6.7L Cummins diesel (model years 2010–2024), offering a durable metal alternative to the factory plastic top. It is supplied as the cap only (the O-ring is not included) and installs using a standard 1 1/8" socket for quick service or swap-outs. Precision machining and a robust finish aim to improve longevity and sealing reliability where the filter assembly meets the housing.

Will this cap fit my Ram 6.7L diesel?

The iFJF cap is compatible with Ram 2500/3500/4500/5500 trucks and Dodge Ram 2500/3500/4000/4500/5000 models equipped with the 6.7L Cummins from 2010 through 2024. Confirm fit by matching the replacement part number 68065612AA with your vehicle’s existing cap or parts list. If your truck uses the same housing design, this cap is a direct form-fit replacement.

• Compatible models: Ram 2500, 3500, 4500, 5500 (2011–2024) and Dodge Ram 2500, 3500, 4000, 4500, 5000 (2010).
• Replacement part number: 68065612AA — match to your original part.
• Form-fit replacement when your housing matches OEM mounting and thread pattern.

How durable and leak-resistant is this replacement cap?

Machined from CNC billeted aluminum, the cap resists cracking and warping better than common plastic tops. Precision threads and a refined sealing surface reduce opportunities for leaks when installed correctly with an appropriate O-ring. For optimal sealing, use a factory-specified O-ring and consider a light film of dielectric grease on threads and seals.

• Material: CNC-billeted aluminum for improved strength and heat resistance.
• Precision machining to minimize fuel seepage around the seal area.
• Recommended: install with a proper O-ring and dielectric grease for best results.

How easy is the installation and what tools are needed?

Installation is straightforward — the cap replaces the OEM cover and is designed for removal and installation with a 1 1/8" socket. Because the cap has clean, flat edges (not rounded), the socket gains better purchase and makes swapping quick during routine filter changes. Note that the package contains only the cap; reuse your existing O-ring or buy a matching replacement if needed.

• Tool required: 1 1/8" socket wrench for removal and installation.
• Package contents: cap only; O-ring not included.
• Tip: apply dielectric grease to threads and O-ring for easier assembly and better seal.

What should I expect in terms of finish and appearance?

The cap ships in a silver finish that complements the engine bay and resists everyday wear. CNC machining yields a clean, consistent surface and crisp edges, providing both an aesthetic upgrade and tactile feedback during installation. Its metal construction also stands up to repeated servicing without the scuffing and deformation plastic caps can show.

• Finish: silver, consistent CNC-machined surface.
• Appearance: crisp edges for easier socket engagement and visual appeal.
• Longevity: metal construction holds up through multiple service cycles.

Who is this for: This iFJF 68065612AA cap is intended for Ram and Dodge owners or technicians who need a reliable, metal replacement for a factory plastic fuel filter housing cover on 6.7L Cummins engines. It's particularly useful when the original cap is cracked, rounded from tool use, or when a longer-lasting service top is desired. If you require the factory O-ring, purchase it separately to complete the installation.
