Good point. I will look at that.

I know you said the filter was loose, but are you 100% sure its the filter that's leaking and not the adapter itself. A deteriorating or pinched o-ring can lead to a adapter leak.

That was my first assumption, so I ordered new seals from LN.
Also a chance to tanks the guys at LN for shipping the o-rings at no cost at all.
So new seals going on regardless, but I always needed the cup to remove the filter.
Never by hand.
