iFJF Fuel Filter Housing Cap for Ram 6.7L Cummins — Black CNC Billet Aluminum, Direct OEM 68065612AA Fit

iFJF's 68065612AA fuel filter housing cap is a CNC-machined anodized-aluminum replacement designed to fit Ram and Dodge Cummins 6.7L diesel filter housings, offering improved durability and a more secure seal than the factory plastic cap.

This replacement cap is made for 2010–2023 Ram and Dodge trucks with the 6.7L Cummins engine that use the 68065612AA-style filter housing cover. Instead of the original plastic cover, this cap is precision CNC billet aluminum with a black anodized finish. It installs using a common 1 1/8" socket and is designed to limit leaks and stand up to longer service intervals in demanding conditions.

Will this cap fit my Ram 6.7L fuel filter housing?

Yes — the iFJF 68065612AA cap is engineered to match the OEM dimensions for Ram and Dodge 6.7L Cummins models that use part number 68065612AA. Before ordering, confirm your truck model year and that your current filter housing uses the same part number.

• Compatible vehicles: 2011–2023 Ram 2500/3500/4500/5500 and 2010 Dodge Ram 2500/3500/4000/4500/5000 with 6.7L Cummins.
• Direct replacement for OEM part number 68065612AA.
• Check your current cap for matching shape and thread size prior to purchase.

How does this aluminum cap improve reliability over the stock cap?

The cap is CNC-machined from billet aluminum, which resists cracking, warping, and UV degradation that can affect plastic covers. The anodized finish adds corrosion resistance, and tighter tolerances provide a more consistent seal to reduce the risk of leaks.

• CNC precision reduces imperfections that can lead to seepage.
• Anodized coating protects against corrosion and road chemicals.
• Sturdy metal construction withstands repeated removal and installation.

How easy is installation and what tools or extras are needed?

Installation is straightforward: remove the factory cap with a 1 1/8" socket and thread the iFJF cap into place. The package includes the cap only; an O-ring is not provided, so reuse your original O-ring or source a replacement if needed. Applying dielectric grease to the threads and O-ring is recommended for improved sealing.

• Tool required: 1 1/8" socket wrench.
• Included: cap only (no O-ring supplied).
• Recommended: dielectric grease for threads and O-ring to ensure a secure seal.

What should I expect in terms of performance and maintenance?

Expect longer-lasting mechanical integrity compared with a plastic OEM cap and fewer sealing issues when properly installed. Routine filter service intervals remain the same; inspect the O-ring for wear each time you change the filter and replace it if compromised.

• Improved resistance to cracking and wear under heat and vibration.
• Maintain normal filter-change intervals and inspect seals every service.
• If an O-ring is damaged, replace it to ensure leak-free operation.

Who is this for: Owners and technicians of Dodge and Ram trucks with the 6.7L Cummins looking for a durable, metal upgrade to the factory fuel filter housing cap. It’s suited for drivers who perform their own maintenance, fleet operators seeking fewer cap failures, and anyone wanting a longer-lasting, corrosion-resistant replacement cover without changing the original filter assembly design.
