Figured out what I did to the old regulator. Be manly, my butt.
It had - key word being had - a black plastic washer inside it, where the connector went in. In my zeal to screw the new manifold in, I crushed it - straight into the pipe of the connector.
That connector is now so tight into the manifold that it'll never come out, I first rounded it trying to undo it with adjustable wrenches, then scored it with channel locks, and it never budged, heh. Ended up having to drill out the plastic.
Guess it is all tight now.
PS - That stiff white plastic-looking "CO2" tubing I picked up locally is junk. It doesn't keep a connection for anything on a barb, leaks like crazy. Don't buy it, get the real stuff from clippard. SO darn glad it is already in the wall and I can't replace it now.
Guess I'll have to spend yet more money figuring out a locking connections to terminate it to, then use clippard tubing to the manifold.
