I don't honestly know if it does fit haha !
BUT I've put my tank on and it's bleeding air through the bleed hole
typical !
Some places say that's a Tank O-Ring but it seems to work fine on my Ego and it's a near brand new one so I don't think it's that.
The other thing it could be is an O-Ring within the ASA but I don't have the Dye Multitool thing to check so back on the shelf it goes. Sorry about that mate, hope you get one !
