2013-2018 Dodge/RAM Cummins w/ 6.7L

Note: Please ensure your fuel filler neck is green plastic with no internal ribbing before ordering.

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.

Great kit to fix a factory problem. Cheap plastic filler neck and chips and cracks over time. The aluminum pieces fit nicely over the neck (even if it’s chipped and missing portions), has another aluminum piece that that slides down the filler neck, and it’s screwed together. I used some blue loctite on the screws. Doesn’t interfere with the DEF cap either. Filler cap fits nicely and has a rubber o ring Great kit, buy one!

Customer photo review of 2013-2018 RAM Billet Fuel Filler Cap Fix Kit (A036/A049)

It fits snug and well. The clearance between the Def cap and the collar are very close which is fine, but if you have a stubby Allen wrench you could probably turn the collar and have more clearance. Overall it seems very sturdy and way better than the OEM plastic filler tube.

Dirty Diesel's Custom LTD absolutely nailed it with their RAM Billet Fuel Filler Cap Fix Kit. The original plastic filler opening on my RAM was broken and missing pieces, but this kit provided a perfect, sturdy replacement made from high-quality materials. It was an easy, affordable fix is far better than the cost and hassle of replacing the entire filler hose. Excellent craftsmanship and real attention to detail; these guys do great work!

Looks great, very well made and the fit was tight but just enough that you know it’s going to work, now I don’t have to stand there and hold the nozzle at a wierd angle so thank you dirty for this

Customer photo review of 2013-2018 RAM Billet Fuel Filler Cap Fix Kit (A036/A049)

Fit perfectly and was a fraction of the price compared to replacing the whole filler spout! Does its job perfectly and keeps the dust out!! Highly recommend this to anyone who has a broken filler spout! Even recommend it to anyone who doesn’t have a broken spout. It is metal and will prevent it from breaking. 10 outta 10 from me.

The "RAM Billet Fuel Filler Cap Fix Kit" worked PERFECTLY on my 2017 RAM 3500 Cummins with the green plastic fill neck! Even-though the description on the website said 2013 - 2015 RAM Cummins. It's a little pricey but the materials appear to be of really good quality. Thank you!

Nice fit. At first, had a problem filling from High Flow Semi truck pump. Nozzle fit but didn't seem to let the nozzle go all the way down. Make sure you get the coil around the nozzle tube down into the filler neck all the way. After I figured that out worked great. Nice product. Wish I had have gotten it before the cheap original plastic broke. Highly recommended for all of our trucks.
