What is this strange pipe and hole on this 750 Veloce inlet manifold?

Hi all,

Please have a look at the pictures of a 750 Veloce inlet manifold that has an extra hole with a pipe in it, 'near' the bottom of (only) one of the four inlet channels.
Any idea what could have been the purpose for that ?
Could this have been original, I never saw this before ?

Thanks for your input.

Fitting for vacuum advance tube on distributor? Looks kind of big for that tho.
Hi Fran,

Thanks, I thought that too before but I wouldn't understand that, the Veloce distributors didn't use a vacuum advance device.


That isnt factory as it appears to be brass... something alfa didnt use. Someone may have needed a port for a brake booster. Good luck
