(T) Unknown leaking pipe, help please!

Thanks to this forum and a new ECU chip, I've got my Cinque going again, but now noticed that there is a leak in one of the pipes leaving the engine. It smells like fuel but it doesnt spurt out with fuel when the car is revved.

I went to the car spares shop to get some more pipe (thinking it was the fuel pipe) but they don't sell any fuel pipes as small as that pipe on the car (outer diameter 8mm).

The guy in the spares shop said it might be the carburettor breather pipe. It connects to the engine at the top, and is secured by a jubilee clip. I've taken a picture of it and the pipe is marked with a yellow arrow. I've put a temporary repair on it, in the picture it looks like a blue bandage.

Any ideas of what the pipe is? Can the leak be fixed or where can I buy a new one?

I think its the fuel return to the tank. It will spurt when you are on the overun. Get it replaced asap.

Where in the world are you?

Cheers
