cut stock elbow hose and double clamp the small end... just make sure its tight.... should be ok.
sameI just did one super tight single clamp on mine. It's working out ok.
Yes, it's worth the risk - IMHO.
I've been running it that way for three years without ever having a problem.
Is it worth the risk? No. Factory Pipe wouldn't have made the elbow if the stock hose worked perfectly. Just get it and forget it.
