Found a used one and it arrived today.
Is this the correct cap for 1995 XJ6? I was running an OEM replacement cap with a different shaped grip handle.
Same part # but didn't look like this one. Why did they change it? Is the newer one vented?
I was surprised it was made in Germany and is non vented OK?

 

That looks the same as mine.
Part number should be EBC8087. Although it looks like replacements might have a differently shaped grip/handle
