049103499g Connector Piece on Cyl Head for Air Shrouded Injectors

My new head is one of the air shrouded injector types, and although I am not using the air shrouded injectors themselves, I do not have the little connector piece which connects the vacuum pipe to the cylinder head.  I need this to allow me to blank off.

Even if I could borrow one to use as a template for making up a blanking pipe out of machined aluminium that would do.  I would need it for a few weeks just.
