iFJF Fuel Filter Housing Cap for Ram 6.7L Cummins — Silver CNC Billet Aluminum Direct-Fit

The iFJF 68065612AA fuel filter housing cap is a CNC-billeted aluminum replacement designed to replace the OEM plastic cap on 2010–2024 Ram and Dodge Cummins 6.7L trucks, improving durability and sealing performance.

This replacement cap fits models using the 68065612AA part number and is engineered to withstand harsh under-hood conditions better than the stock plastic cover. Machined from solid aluminum, the cap resists cracking, warping, and heat-related deformation while providing a precise mating surface for the filter assembly. It installs with basic hand tools and is intended as a direct fit for Ram 2500/3500/4500/5500 and compatible Dodge truck variants listed with the Cummins 6.7L diesel engine.

How does this cap improve reliability under the hood?

The iFJF cap brings a tougher material and tighter machining tolerances compared with OEM plastic caps, which can become brittle and leak over time. CNC billet aluminum resists impact, high temperatures, and repeated removal without degrading.

• Precision CNC machining reduces the risk of uneven sealing surfaces that cause leaks.
• Aluminum construction resists cracking from vibration and thermal cycling.
• Durable finish is less susceptible to chemical and fuel exposure than plastic.

Will it fit my Ram or Dodge with a 6.7L Cummins engine?

This cap is made to match the OEM 68065612AA specification and fits 2010–2024 Ram 2500/3500/4500/5500 trucks and compatible 2010 Dodge Ram models equipped with the 6.7L Cummins diesel. Confirm the part number and visual shape of your existing cap before ordering to ensure compatibility.

• Compatible part number: 68065612AA.
• Fits Ram 2500/3500/4500/5500 model years 2011–2024 and certain 2010 Dodge Ram pickups.
• Designed for the Cummins 6.7L diesel engine filter housing.

How do I install this replacement cap and what tools are needed?

Installation is straightforward: remove the old cap with a 1 1/8" socket and hand-tighten the new cap in place. The cap ships alone (O-ring not included), and we suggest using dielectric grease on threads and seals to improve longevity and prevent leaks.

• Tools required: 1 1/8" socket wrench and basic hand tools.
• Package includes: cap only — O-ring must be reused from your original part or purchased separately.
• Apply dielectric grease to threads and O-ring for a better seal and easier future removal.

What performance or maintenance benefits can I expect?

Switching to a machined aluminum cap reduces the chance of fuel seepage and cap failure, helping maintain a stable filtration environment for your diesel engine. The stronger cap reduces maintenance interruptions caused by cracked or warped plastic covers.

• Improved seal stability reduces the likelihood of fuel leaks.
• Longer service life compared to OEM plastic caps means fewer replacements.
• Easier repeated removal without losing integrity for routine filter service.

Who is this for: The iFJF 68065612AA replacement cap is aimed at owners and technicians who service Ram or Dodge pickups with the 6.7L Cummins diesel and want a more durable alternative to the factory plastic housing cover. It’s appropriate for fleet vehicles, work trucks, or owners who perform regular fuel filter maintenance and prefer a metal cap that resists heat, vibration, and chemical exposure. Verify your vehicle’s part number and O-ring condition before purchase; this listing includes the cap only.
