Vac hose size?

So replacing the injectors/injector seals, I broke more than a couple vac lines and went to get some replacement. I took along one of the old pieces and 5mm has a slightly smaller ID than the old pieces. i come home and test fit the hose before I cut it, expecting it to be snug. It's loose! Do I need 4mm hose, or will it seal well enough...[?] Mazdatrix lists 3.5mm and 6mm hose, but the pieces I removed look bigger than 3.5mm, and are definitely smaller than 6mm.
