Someone in Chicago to help with Maplenoll Ariadne?

I have a Maplenoll Ariadne with the Signature kit with scud air chamber. My air handling is not good because I can hear leaks at the junctions of the hoses. Is there someone in the area who could help me with this? I tried buying hose clamps at Home Depot but they are too large. Any help would be sincerely appreciated and compensated. I have both the original pump and another quiet pump. Bob
