From what I can see on the Fiat parts info the fuel cap, with seal is a single unit.
However I suggest you look carefully at your fuel cap and extract the seal if possible.
It is very unlikely that the seal is a "one off" Barchetta only item and you should be able to source a replacement seal from a company that specialises in "O" rings and other types of seals.

Well it’s over 6 years since I posted this question, but as it popped up as an advisory on my otherwise perfect mot, I thought I’d do something about it!
I measured up and ordered these for Vauxhalls from Amazon https://amzn.eu/d/f1hIdmG and they fit perfectly
