I was given a Speedaire air regulator (4ZK90 - metal bowl with filter). When I first hooked it up, it leaked like crazy. I pulled the bowl off, cleaned things up, and replaced the o-ring. It still leaks. What am I missing with this thing? When I turn the bowl to lock it in place, it has a tremendous amount of wiggle to it. Nothing is broken or bent though. Is this normal for these Speedaire filters? Do they not lock into place very snuggly?
