Reply To: New Huma Regulator Issues
Does the huma regulator require a vent hole drilled? I have found that a highly polished inside tube wall will allow air to leak out of the vent hole. You have to rough the surface with a 4-500 grit sandpaper to give the o-ring a place to bite. Sounds odd that you rough the surface but a mirror finish lets air pass. I’m a Robert Lane regulator distributor and installer. I have little experience with the Huma.
