Triumph knows about it. I sent them even more photos, high-res, when I first noticed it. And which they were happy to receive. The crack is really thin. I would probably not even have noticed it if I had not scratched off a tiny baked-on morsel right next to it with my fingernail. It would be pedantic, IMHO, to claim a replacement at this stage, and I doubt I would succeed. It functions, does not leak, and you must look for it to see it. I only posted to share the information so that others can have a good squiz in case they might be experiencing the same.
