Upgrade your Ram 6.7L Cummins diesel with the iFJF billet aluminum fuel filter housing cap 68065612AA. Designed to replace the OEM plastic cap, this cap emphasizes durability, precision, and a clean engine bay aesthetic with a distinctive green finish. It aims to fit 2010–2019 Ram 6.7L diesels in the 2500, 3500, 4500, and 5500 series, offering a confident upgrade for daily driving, long trips, or heavy-use scenarios where reliable filtration matters.

Compatibility and fit

This cap is a replacement for the 68065612AA fuel filter housing cap and is intended to work with your existing filter assembly. For best results, verify the part number and your engine configuration before purchasing.

Key benefits at a glance

• Sturdy billet aluminum construction that withstands heat and vibration
• Precision CNC machining delivers a consistent fit and reliable sealing
• Green anodized finish adds corrosion resistance and a rugged look
• Easy installation with a standard 1 1/8 socket wrench
• Designed to work with your filter system to support a tight seal when used with the existing O-ring and dielectric grease

What’s included and how to install

• Cap only in the package
• Your filter kit includes the O-ring; this cap does not include it
• When installing, apply dielectric grease to the threads and O-ring for a better seal

Durability, reliability, and real-world use

Machined from billet aluminum rather than plastic, the cap resists deformation under heat and vibration and provides a smooth threading surface for a clean install. The green finish helps resist wear in dusty or harsh environments, making it suitable for daily driving, fleet use, or long highway runs. While not a guarantee of performance, the design aims to minimize fuel leaks and support stable filtration system operation over time.

Real-life scenarios

In everyday commuting and challenging road conditions, a robust cap can reduce maintenance interruptions. It pairs with your existing filter hardware to offer a straightforward upgrade path without altering the rest of the intake system. If you frequently tow or drive in dusty areas, a strengthened cap may help maintain filtration integrity between service intervals.

Note that this is a replacement part intended to upgrade durability and sealing where the OEM cap is plastic. It offers a potential improvement in how the fuel system holds together during operation, with no promises about performance gains.
