It seems it may also in fact be the fuel filler neck and not the cap - https://www.s2ki.com/forums/s2000-un.../p1546-403110/
But I'd start with the cap as you did...
BTW - Google is your friend!

If the cap doesn't fix it, here is the TSB on the filler neck issue which affects only certain ap1s (see list in TSB). I had to replace the filler neck on both of my ap1s.
