Review on Magnetic Diesel Fuel Cap Accessory for Dodge RAM TRUCK 1500 2500 3500 (2013-2018) 6.7 CUMMINS EcoDiesel | New Easy Grip Design | Includes 2 O-Rings by Roy Ramos

Much better than the crappy plastic cap that was on my 2016 Ram 2500 Laramie Longhorn. It comes with two different sized o-rings. The thicker one was on the cap but was too tight so I put on the thinner one and it's perfect. The magnet is very strong and sticks firmly to the fuel filler flap hinge as shown in the photo. Should have gotten this a few months ago.
