iFJF Fuel Filter Housing Cap for Ram 6.7L Cummins (2010–2019) — CNC Billet Aluminum, Green

iFJF's 68065612AA replacement cap is a CNC-billet aluminum fuel filter housing cover designed to replace the original plastic cap on 2010–2019 Ram 6.7L Cummins trucks.

This precision-machined cap replaces part number 68065612AA and offers a durable metal alternative to the factory plastic cover used on Ram 2500, 3500, 4500 and 5500 diesel models. The cap ships as the cap only (O-ring not included) and is sized for removal and installation with a 1 1/8" socket. Its CNC construction aims to deliver tighter sealing and longer service life compared with stock plastic caps.

Will this cap fit my Ram 6.7L fuel filter housing?

The iFJF cap is made to match the OEM 68065612AA specification for 2010–2019 Ram 6.7L Cummins engines. It replaces the factory housing cover directly and uses the same mounting interface, so no modification to the housing is required.

• Compatible models: Ram 2500, 3500, 4500, 5500 with 6.7L Cummins (2010–2019)
• OEM replacement number: 68065612AA
• Direct-fit design: installs in place of the original cap

How does the CNC-aluminum cap compare to the original plastic cap?

The CNC-billet aluminum cap is designed for improved rigidity and better resistance to cracking or warping over time compared with plastic. The machined threads and sealing surface provide a stable contact with the filter housing, reducing the chance of leaks when installed correctly.

• Material advantage: CNC aluminum vs. factory plastic
• Durability: higher resistance to heat and mechanical stress
• Sealing: precision machined surface to reduce leak risk

What tools and steps are needed to install this replacement cap?

Installation is straightforward and requires a 1 1/8" socket wrench to remove the stock cap and install the new iFJF cap. The product ships as the cap only—your original O-ring must be reused or replaced separately; use dielectric grease to help protect threads and improve the seal.

• Required tool: 1 1/8" socket wrench for removal and installation
• O-ring: reuse OEM O-ring or purchase a compatible replacement
• Seal prep: apply dielectric grease to threads and O-ring for better sealing

Does this cap prevent leaks and improve long-term reliability?

Precision CNC machining increases dimensional accuracy, which helps create a consistent threading and sealing surface to reduce fuel seepage. While proper installation and a good O-ring are essential, the cap's metal construction resists deformation that can lead to future leaks.

• Precision-machined threads reduce uneven contact
• Aluminum resists distortion from heat and vibration
• Requires correct O-ring and installation for optimum sealing

Who is this for: This replacement is aimed at Ram 6.7L Cummins owners who want a more robust, long-lasting cover for their fuel filter housing than the factory plastic option. It's a good choice for technicians, fleet operators, or owners performing routine maintenance who prefer a metal cap for improved durability and consistent sealing, provided they can supply or reuse the appropriate O-ring.
