Hi Dave,
This is a Weber manifold, so it doesn't have any existing hose.
I tried the look for the matching nut thing ( in four hardware stores ) and
nothing matched. Frank suggested drilling and tapping for a standard
threaded pipe and then sing hoses and clamps. That's probably what I'll end
up doing.
Thanks,
Robert
