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 Tom Plowman

Let me start by saying that I've tried two other models of upgraded gas caps here at Revain and this one fits my 2016 Ram EcoDiesel perfectly (although I hear there is a difference in the fuel tank). neck diameter) and this can be easily removed (in contrast to almost all others). This one also looks very nice and has removed the extra weight. At first I thought the magnet was weak as it ONLY sticks to the inside surface of the fuel filler flap. There should be a layer of plastic or aluminum on top of the magnetic steel at this particular spot. THE FIRST TIME I used it it got stuck there and I hit the filler where I put the cap in just enough to move the door an eighth of an inch and the cap fell onto the concrete and took out the shavings, of which a is good ending. laugh! Install the cap on the HINGE of the fuel filler flap where it will be held! I'm not sure what will happen if you leave it hanging from the sling; The wind can close the door when you drive, and the design of the hinges leaves no room for a cover. Anyway, this is not the fault of the lid designer/manufacturer. If you really want it to stick to the flat vertical surface on the inside of the fuel filler flap, you can glue another neodymium magnet to the inside of the fuel filler flap to hold the two magnets in place. together. If you do this, just make sure you orient the second magnet properly so its poles stick together. ;-)
