Right..I agreed inside the elbow there isn't a lot of room to work. That can happen when working on things, I call it ..."less than ideal". At these times we have to perservere and overcome the situation. Or do the manly thing and buy more tools to make the job easier.
As for the looseness vs the other..they aren't 100% comparable, one is smaller than the other and the world isn't perfect. Maybe changing the plastic clip will help. Expecially if you reefing on it broke it internally and you can't see it until you pull the fuel line off. In my experience though, they aren't overly snug and the o-rings fix up the issue.
