The capless fueling system on 4th Gen RAM trucks has a major Achilles heel: it leaves your fuel tank vulnerable to moisture, dirt, and debris. We’ve solved this issue with our lineup of Dirty Billet Fuel Caps. Designed specifically for the 2013-2018 Cummins and 2014-2018 EcoDiesel, both of our cap options feature a precision O-ring seal and an integrated 20lb pull-strength magnet to keep the cap secured to your fuel door hinge while you fill up.

Choose Your Solution:

• OEM Filler Cap (A049): A straightforward, precision-machined aluminum cap that slides into your stock filler neck to keep contaminants out.
• Fix Kit Cap (A036): Designed to solve the common issue of the green plastic filler neck breaking, especially in freezing temperatures. This kit uses a high-strength sleeve and split clamp system to reinforce or repair a broken neck, providing a durable interface for pump nozzles.
