I think the balls are a "ROLL OVER" valve to shut fuel off on vehicle roll over. Hope this helps.
Hmmm,interesting,Is this some new regulation..?
I've taken apart many fuel cells/tanks, fill tubes, and never seen this on any modern fuel tank. Have seen anti-siphon valves in tank fill tube/cap assembly. Modern tank caps are not vented so can't understand why a roll over shut off valve in fill tube would be useful..?
Its a 2016, and still under warranty ? I'd bring it back.
If not and you want to fix it yourself...
Have seen debris from installation floating around in new tanks. Cutouts that were not cleaned out after holes were cut, chunks of tubing, hose, etc...
Have also seen many fill tubes kinked so as to cause very slow fill ups. Also have seen vent lines kinked. Some California compliant tanks have evaporative emission systems in their vent lines.
If it were mine, and warranty can't take care of the problem, I'd drop the tanks and clean them out, and remove any obstructions. Can't see how little green balls in your fuel tanks could help you out at all. Can tell you with certainty, my tanks have no little green balls in the fill pipe. My tanks fill up fast, just like a car fuel tank.
