## Description

For all Dodge Ram Diesels 2013+ with "capless" fuel fill. (May not fit 2019) This trick looking billet aluminum diesel fuel cap and DEF cap accessory will enhance the look and feel of your new truck. More importantly this cap will give you peace of mind that your fuel tank is staying clean by keeping dirt and debris out. The rubber o-ring seals off the fuel filler area and provides a snug fit. The strong magnet on the backside allows you to easily set it aside during fill ups, just stick it to any metal part of the truck. Eliminate any concern about dirt getting into your fuel tank, this is a fast, simple, effective design and looks great too!

Review: Quality Caps - I am happy with my caps. They look great and fit good on my 2025 RAM 2500.
Review: Awesome! Just don't try to... - First let me say that I have tried two of the other models of upgraded fuel caps here on desertcart and this one fits my 2016 Ram EcoDiesel perfectly (though, I hear there is variance in fuel filler neck diameter) and this one is easy to grab in order to remove it (unlike just about all the rest). This one is also very nice looking and has any excess weight removed. I first thought that the magnet was weak as it BARELY sticks on the inside surface of the fuel filler door. There must be a layer of plastic or aluminum over the magnetic steel in that particular place. The VERY FIRST TIME I used it, I had it stuck there and I bumped the filler door where I had stuck the cap, only enough to move the door an eighth of an inch and the cap fell to the concrete and took a chip out of that nice finish. LAME! SOOOO... don't be an idiot like me! Stick your cap to the fuel filler door HINGE, where it sticks like a champ! I'm not sure what would happen if you drove away with it stuck to the hinge; the wind may blow the door closed as you drive and hinge design may not allow enough space for the cap to stay. Not the cap designer/manufacturer's fault, either way. If you really want it to stick to the flat verticle surface on the inside of the filler door, you could epoxy another neodymium magnet to the inside of the fuel door so the two magnets will hold together. If you're going to do this, just make sure you orient the second magnet properly so that the poles want to stick to each other. ;-)

### ⭐⭐⭐⭐⭐ Quality Caps
*by K***R on January 2, 2026*

I am happy with my caps. They look great and fit good on my 2025 RAM 2500.

### ⭐⭐⭐⭐⭐ Fuel filler cap - Something I didn't know I needed on a 45k truck.
*by A***R on May 12, 2019*

I have the Ram 2500. So i was torn between this cap and the one without the lifted portion, to allow easier removal. I went with this one bc I didn't want to have to struggle to remove the cap (after reading reviews for the other cap that seemed to be the main issue with it). Although, after taking this cap on and off I'm not sure the extra money I paid for this cap is really worth it, but then I haven't used the other cap and there wasn't a problem with either removing it or putting it on. During the winter when I'm wearing gloves I'm going to be extremely glad I bought this one and not the other one! (Just a thought if you live in a freezing climate). I also found it interesting that this cap came with a "thinner o-ring" in the package that wasn't mentioned on the add. I don't think it's needed and I would be afraid that the cap would fall out if I were to use it. It appears to fit snugly as is. That being said the cap itself appears to be well made and all one piece. I now don't have to worry about getting anything into the diesel tank that isn't supposed to be there, like when i'm filling the def and there's an over spray or washing the truck as I noticed that water did in fact get into the fuel filler compartment (which is what sent me on a search for something like this.) The magnet holds the cap firmly in place when removed. Very happy with my purchase. Doesn't appear that I will need to ever replace this item. (unless I lose it)
