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.
