Description

5th Gen Ram Cummins Fuel Cap – CAWRFC

From C59 AutoWorks – Printable Automotive Parts and Accessories

 

Protect your Ram’s fuel system from sand, dirt, and water with this precision-fit fuel cap. Let’s face it, some factory designs just don’t make sense. When a friend needed a solution and none were available, I grabbed the calipers and designed one. 

 

A year later, I’ve refined the design to be even easier to print, now support-free!

Whether you’re an overlander, a tradesperson, or a daily driver, this $1.14* print can save you from costly fuel system issues.

 

💡 Perfect For:

  • Keeping your rig’s fuel clean and safe
  • Overlanding, work trucks, weekend fun, and more!

🔧 How to Use:

  • Insert directly into the filler neck, it's slightly tapered to fit securely.
  • Optional TPU tether, or use a paracord.
