Don, thanks for posting those pics of that cap. Do you happen to have a part number for it? I would like to add one to my truck.

And Bumpy, my 2012 Ford F-150 work truck has a capless fuel filler system also so this arrangement is definitely not unique to Ram. :R

And that F150 doesn't have a DEF fill port right next door to the diesel fill port either just waiting for a spill to occur. I would most definitely have the MOPAR diesel protective cap.

Just like the F150's cap less filler, the Ram has two flaps in the filler port. One on the outside which keeps the debris out, and another deep down in the filler that requires a fair amount of pressure to open. In order to even put fuel in your tank from a gas/fuel can, a special funnel that comes with the truck is required so the it can open this second flap since most gas/fue can spouts are not long enough.

Also, in between these two flaps is a hole in the filler neck. If any water gets passed the first flap then it will seep out of this hole to the ground if there is nothing to open the second flap. In other words, you would have to want to put water in your tank to get it in there because it would require you to use the special funnel to do it.
