Those hoses are notorious for being hard to source. Separate it entirely into 2 pieces where it cracked then use larger diameter silicone hose and a couple of clamps. Tighten them when the entire hose is in place.

You could try Alfaholics for some of that which you show in your picture. Scroll down to near the bottom.

There may have you want at Day and Whites. They have an early TS GTV as a spares ship.

I used self sealing tape on the torn flexi part of the air intake hose about 6 months ago and it's still airtight.

I'd try Dave at Alfa Romeo City, he'll have loads of these and he ships worldwide.

If the part isn't listed just email him and he'll get back to you.

Compare the price with that from Alfaholics. Is the OP’s 916 CF1 or CF2? It is an early one.
