Aluminum Gas Cap & Filler Kit w/ Vent

2 reviews Write a Review

This is the GenRight Billet Aluminum Gas Cap & Filler assembly. It's compact design solves a problem for stretched Jeeps with big tires! It is mounted above the frame inside the rear inner fender well (as pictured).

The entire assembly is CNC machined. The gas cap has an o-ring seal under it, so as you remove the cap it prevents dirt from getting in the filler tube or threads.

This is the same fuel filler we use on our GenRight Jeeps, and it works great!


  • Removes the fuel filler from the rear corner of the Jeep.
  • CNC machined from Aluminum alloy.
  • Hand TIG Welded.
  • Knurled gas cap has an O-ring seal to keep water and dirt out.
  • Designed to fit all models of GenRight Jeep gas tanks.
  • Compact size keeps it away from the tire. 
  • Easy to reach with wheel openings trimmed to fit bigger tires.
  • This model includes specific hose sizes. Choose your application carefully.
  • We do offer a "universal" option with multiple hose sizes to fit any tank vent/fill configuration.
  • Includes all necessary hardware to install. 

Additional NOTES:

  • Includes fuel rated hose and new hose clamps.
  • Because of the mounting location, you may need to trim some of the inner fender well sheet metal (as pictured) to fit this product.
  • This product may not comply with your local or State emissions regulations (CA requires use of your stock gas cap).

    Simple and smart

    This was the perfect solution after stretching my TJ. I probably shouldn't say this but my local Smog guy didnt' care that this was on the jeep. Fills pretty easily depending on the gas station. Great product and fast delivery, thank you.

    Clean Look

    I was going to run the factory filler but realized how much material I was losing in the corner guard after stretching the wheelbase and to cut a big hole for the filler would have weakened the corner in my opinion. This GenRight billet fuel filler was super easy to install and works well for my setup. Glad I went this route.
