| Possibly
Not wishing to contradict Neil, it depends. There was a transition period around '91 where the factory moved from the aircraft style filler and the hinged lockable job. The only seal on these was a green o-ring which never did a complete job, and needs gunking up with lots of sealant to prevent seeping.
On mine, I tried fitting the additional rubber ring ring 'twixt cap and tank and it just would not work. I think that later cap assemblies were modified to allow the black seal as well as the o-ring.
