Just found these rattling around in my fuel tank. My first thought was internals from a locking cap but there’s a similar diameter space inside around where the pipe comes out the bottom of the tank, any ideas? Everything else looks tickety boo thankfully!
Looks like fuel cap parts to me. The lugs on the left hand piece look like they lock into your fuel filler.
Looks like filler cap guts to me - even has the locating nubs for the tabs on the neck. Edit: too slow off the mark! Sent from my iPhone using Tapatalk
