Was finally able to construct a hose within a hose to replace the deteriorated existing set up. So the moral of the story is, if you have an Alpine supercharger, you might want to check the condition of yours. I also came across the following email address: sales@performancesi.com which I used a while back to replace the 5 pound pulley. So I gave it a shot but never got a response. That company apparently purchased Alpine and was supplying parts for a while. If anyone reads this and has information as to where we can now obtain alpine supercharger parts that would be a big help.
