Air Intake on Lycoming 0-320

I have an RV-9A with a Sam James Cowl and a Lycoming 0-320 engine. The airbox appears to be the standard Van's airbox. Does anyone know what the hose looks like, or the part # is that hooks the cowl intake to the airbox. I bought airplane with a scat tube between the two but when you lower the cowl and reinstall it, it will not hook back up. Surely someone knows what that hose looks like or a part #. I think air is leaking from the scat tube and causing a high pressure in the bottom of the cowl resulting in a higher CHT on #1 and #3 cylinders. I called Sam James but did not get a return phone call. Any ideas would be appreciated. Thanks

Intake tube

I used some multi-ply silicone hose with fabric reinforcement, clamped the front end to the James inlet. Fits the James air filter perfectly and provides a seal without clamping at the filter.
