iFJF Fuel Filter Housing Cap for Ram 6.7L Cummins — Red CNC Billet Aluminum, Durable Leak-Resistant Fit

iFJF 68065612AA is a CNC-billeted aluminum replacement fuel filter housing cap for Ram 6.7L Cummins trucks that provides a durable, leak-resistant upgrade to the factory plastic cap.

This replacement cap fits Ram and Dodge trucks equipped with the 6.7L Cummins diesel (model years listed below) and is designed to withstand heat, vibration and repeated service better than the stock plastic cover. Finished in red, the cap both refreshes the engine bay appearance and delivers improved sealing through precision machining. The package includes the cap only; the factory O-ring and filter are not provided.

Will this cap fit my Ram 6.7L diesel?

Yes — the iFJF 68065612AA replacement cap is built to match the original factory fit for many Ram and Dodge trucks with the 6.7L Cummins engine. Confirm fitment by matching the replacement part number and your vehicle year/model.

• Compatible with Ram 2500/3500/4500/5500 models from 2011–2023 and certain 2010 Dodge Ram/Cummins applications.
• Replacement part number: 68065612AA — verify against your OEM part.
• Designed to mate with your existing filter assembly and O-ring (O-ring not included).

How is this cap better than the original plastic cap?

The cap is CNC-machined from billet aluminum for superior strength and heat resistance compared with injection-molded plastic. Precision machining produces a true sealing surface to reduce the chance of fuel seepage and to withstand repeated installation and removal during maintenance.

• CNC billeted aluminum construction improves durability and longevity.
• Precision threads and sealing face minimize vibration-induced leaks.
• Red anodized finish resists corrosion and enhances engine-bay appearance.

What tools and steps are needed to install it?

Installation is straightforward: remove the old cap with a 1 1/8" socket and hand-thread the new cap into place. The replacement was designed without the rounded OEM edges so a standard socket fits securely for quick removal and installation.

• Tool required: 1 1/8" socket wrench (or compatible socket).
• We recommend applying dielectric grease to threads and the O-ring for improved seal and easier future removal.
• Check and replace the filter O-ring if aged or damaged — O-ring not included with cap.

Will this cap prevent fuel leaks and improve reliability?

While no part can eliminate all possible issues, the machined aluminum cap reduces leak risk by providing a flatter sealing surface and more durable threads than the OEM plastic cap. It’s intended to maintain a stable seal over many service cycles and under harsher conditions.

• Precision machining reduces irregularities that cause seepage.
• Stiffer material resists deformation from heat and torque during service.
• Proper installation and fresh O-ring maximize leak prevention.

Who is this for: The iFJF 68065612AA cap is aimed at Ram and Dodge owners who want a longer-lasting, service-friendly replacement for the factory plastic fuel filter housing cap. It suits fleet technicians, DIY mechanics, and performance-minded truck owners who prefer metal components for durability, improved sealing, and a refreshed engine-bay look. Before purchasing, confirm your truck’s part number compatibility and plan to reuse or replace the filter O-ring during installation.
