Are you talking about the rubber hose size? or the steel line size? There are many types of vac blocks, and many different sizes. Post a pic of your set up.

The vacuum port for the brake booster is 3/8. I am pretty sure

you need:
1/4 for 3 ports
3/16 for one port
3/8 for one port
Your local parts store should have plenty on the roll in these sizes. I took the old hoses off my vacuum block, and took it with me. If you have the block on you you can test fit the hose to make sure the outside diameter is not too big on any of them. It would also be a good idea to replace the gasket under the vacuum block if its old, you can buy the gasket off the vendors on here or you can make one yourself. Good luck man!
