Engine vacuum pipe?

Question

I need to replace the vacuum pipe on a vauxhall vectra 2.0 ltr DTI, The trouble is i cant seem to get the right size. The vauxhall dealer just wanted the car in the garage (£££) and tried to tell me that they dont stock the pipes, When i asked if they could order them in he said no !!!!!

What i really want to know is if the replacement pipe has to have the same internal diameter as the old pipe ?? I need 2mm but can only find 3,4 & 5mm.
