Hi guys I need a little help with my Puncher Breaker. Its leaking air from the valve block after fitting a Huma-Air regulator, I have tried emailing Kral themself (ha that's a joke). I have looked at there own breakdown plans on whats what and where it goes and the part number and so on, now I don't know it the breakdown book I'm looking at is for the Mk 1 but there are extra o rings part number At 23 added and a manometer and o ring part number At26 & 27.

thanks in advance just for looking at this
