XJMOTO Fuel Cap Magnetic Billet Aluminum Green Compatible with 2013-2018 Dodge Ram 1500 2500 3500 Pick-up Truck

Love this cap. Fits tight and works great. Have this one and the blue DEF one

2015 RAM 3500

This was very nice, it just didn't fit my 2022 RAM 2500

Perfect fit and looks great

This is a nice looking cap if you seem to get a good one. I am on my third one and sending my second back. The first one came with a big scratch across the front of it and the second one has a few sharp burrs along the right side (see pic, right cap). The biggest difference is the color variance. You can see the cap on the left is a nice diesel green color where the right one is more of an olive green color. Not sure why that is. My first 2 caps shipped from one Amazon warehouse and my third (which is the left one that I am keeping) shipped from another warehouse. So all in all it's a nice looking cap and fits my 3.0 Duramax capless fuel fill perfectly using the larger of the supplied o-rings. I do plan on taking the screw out of the magnet and adding some thread locker to it so it doesn't accidentally back out and end up in my fuel tank.

The reason only 4 stars is the magnet is weak and will barely hold it as pictured. I wouldn’t trust it to stay in place. It also doesn’t fit my Chevy 1500 Duramax and it’s not advertised to, however some reviews say it does. That doesn’t affect my rating, just want people to know before you order.

I'm using this on my 2023 GMC Sierra 1500 diesel. It fit perfectly and keeps dirt and water out of the fuel filler.

Very loose fit. Very weak magnet, won’t stick to the fuel door.
