I replaced the O rings on the piston in the regulator but it still leaks out that hole. This is the hole i am talking about. (The O ring on the tank is fine also and it leaks the same with the pressure regulator screw all the way in or all the way out....im not sure what is causing this)
To be honest, im not even sure why that hole is there? It's not threaded so there was never a screw in it to seal it?
Another thing I noticed to make me even more confused is some don't even have that hole? I dont understand? Clearly its supposed to be there in mine above because the words are spaced to make room for it
