iFJF Fuel Filter Housing Cap for Ram 6.7L Cummins — Green CNC Billet Aluminium, Leak-Resistant

iFJF 68065612AA is a CNC-billeted aluminum replacement fuel filter housing cap designed to fit 2010–2024 Ram/Cummins 6.7L diesel models, offering a durable, leak-resistant alternative to the OEM plastic cap.

The OEM plastic fuel filter cap can crack, warp, or leak over time; this iFJF replacement cap is machined from solid aluminum and finished in green to match your engine bay while improving long-term durability. It installs with common hand tools and is sized to the original 68065612AA specification. This listing includes the cap only (O-ring not included), and it’s compatible with multiple Ram and Dodge diesel applications.

Will this cap fit my Ram 6.7L diesel?

This iFJF cap is made as a direct-size replacement for part number 68065612AA and fits 2011–2024 Ram 2500/3500/4500/5500 models and 2010 Dodge Ram 2500/3500/4000/4500/5000 with the 6.7L Cummins diesel engine. Confirm fitment by matching your existing cap’s part number or the housing thread size.

• Compatible part number: 68065612AA.
• Fits Ram/Dodge 6.7L Cummins diesel model years listed above.
• Measure/verify thread and housing before purchase if unsure.

How is the iFJF cap different from the OEM plastic cap?

The iFJF cap is CNC milled from a single billet of aluminum, which resists cracking and deformation better than injection-molded plastic. Its precision machining produces a tight thread fit to reduce the risk of fuel seepage and improve longevity in high-heat engine bays.

• Material: CNC billet aluminum for increased strength.
• Precision threads reduce potential leaks.
• More resistant to heat, chemical exposure, and impacts.

How do I install this replacement cap?

Installation is straightforward: remove the old cap with a 1 1/8" socket wrench and hand-thread the iFJF cap into place. Apply dielectric grease to the threads and O-ring (O-ring not supplied) to help ensure a reliable seal and easier future removal.

• Tools needed: 1 1/8" socket wrench or appropriate hand tool.
• Recommendation: use dielectric grease on threads and O-ring.
• Package includes cap only; reuse OEM O-ring or purchase replacement separately.

Will this cap help prevent leaks and improve reliability?

While no part eliminates all failures, the iFJF cap’s machined construction and accurate thread profile reduce the likelihood of seepage compared with cracked or worn plastic caps. Proper installation with a good O-ring and thread grease is essential for best results.

• Engineered to minimize fuel seepage through precision machining.
• Durable material reduces risk of cracking under stress.
• Long-lasting finish helps withstand engine-bay conditions.

Who is this for: The iFJF 68065612AA cap is aimed at Ram and Dodge owners with 6.7L Cummins diesel engines who want a stronger, longer-lasting replacement for the factory plastic fuel filter cap. It’s ideal for drivers who perform their own maintenance, fleet operators seeking durability upgrades, and anyone replacing a damaged or leaky OEM cap. Note: this listing is for the cap only; confirm O-ring availability separately before installation.
