Billet Front Fuel Filter Housing Cap Upgrade
Fits 2010–2024
The factory front fuel filter housing cap on the 6.7 Cummins is known for becoming a problem point over time. The original plastic cap can strip, deform, leak, or round off, especially after repeated filter services and engine heat cycles. Our billet replacement cap eliminates those issues and provides a long-term solution for reliable sealing and easier maintenance.
Why Upgrade Your Fuel Filter Cap?
The OEM cap commonly leads to:
-
Fuel leaks around the housing
-
Damaged or stripped threads
-
Rounded hex head from tool slippage
-
Air intrusion causing hard starts
-
Overtightening due to poor sealing
Once the factory cap distorts, it often never seals properly again.
Premium Billet Replacement Design
This upgraded cap is engineered for durability and serviceability:
✔ Machined billet construction – far stronger than the cast factory piece
✔ Precision threads – resist cross-threading and wear
✔ Flat sealing surface – ensures consistent O-ring compression
✔ Larger wrench engagement – easier removal during filter changes
✔ Reusable for repeated services
Built to handle heat, vibration, and frequent maintenance — ideal for work trucks, tow rigs, and performance builds.
