iFJF Fuel Filter Housing Cap for Ram 6.7L (2011–2024) — Red Billet Aluminum, 1-1/8" Socket Fit

iFJF 68065612AA is a CNC-billet aluminum replacement fuel filter housing cap designed to fit Ram 6.7L Cummins diesel trucks (2011–2024), offering a durable, service-friendly upgrade in red.

This replacement cap swaps in for the factory plastic cover on the 68065612AA fuel filter housing found on Ram 2500/3500/4500/5500 and certain Dodge Ram models, providing a stronger seal, improved longevity, and a serviceable, wrench-friendly shape. Machined from billet aluminum and anodized red, the cap resists deformation and heat better than stock plastic, and installs using a standard 1-1/8" socket. The package includes the cap only; an O-ring is not supplied because most replacement filter kits include new seals.

How does this aluminum cap improve durability compared to the OEM plastic cap?

The CNC-billeted aluminum construction resists cracking, warping, and thread wear that can occur with prolonged exposure to heat, vibration, and fuel. Anodizing adds corrosion resistance and a finished appearance. Together these features reduce the chance of fuel leaks and the need for repeated replacements.

• Billet aluminum body withstands higher temperatures and impacts.
• Precision threads reduce cross-threading and ensure consistent torque.
• Anodized surface prevents corrosion and maintains color under road conditions.

Is installation straightforward for a DIY owner?

Yes — the cap is designed to be user-friendly and installs with common tools. The underside is shaped for a 1-1/8" socket, so removal and replacement are quick during routine filter service. For best sealing performance use a fresh O-ring and dielectric grease on threads and O-rings.

• Requires a 1-1/8" socket for installation and removal.
• Replace or reuse an O-ring from your filter kit; cap does not include one.
• Apply dielectric grease for easier future service and improved sealing.

Will this cap fit my truck and which part number does it replace?

This cap is made to replace part number 68065612AA and fits 6.7L Cummins diesel applications listed by model years. Confirm compatibility against your vehicle’s filter housing and OEM part number before purchasing to ensure a correct fit and function.

• Direct replacement for part number 68065612AA.
• Compatible with 2011–2024 Ram 6.7L 2500/3500/4500/5500 models and select 2010 Dodge Ram variants.
• Intended for use with standard fuel filter housings—verify fit before installation.

What maintenance or best practices should I follow after installing it?

Routine inspection during filter changes helps catch seal wear or thread damage early. Always use a quality replacement O-ring and lubricate sealing surfaces to maintain a leak-free system. If you experience difficulty threading the cap, stop and inspect for debris or misalignment to avoid damaging the new cap.

• Inspect and replace the O-ring during each filter service.
• Use dielectric grease on threads and seals to protect against fuel intrusion and ease removal.
• Torque sensibly with a socket—avoid overtightening to protect housing components.
