There are a few different sizes, but 4mm or 3/16" line is most likely what you're looking for. When you go to the Autoparts store, just eye-ball the measurements. The exact size isn't important, as long as it fits on the whatever fittings you have. If you buy the it online, the website where you buy it from should specify the size. High Temp Silicone (hitempsilicone.com) sells quality silicone vacuum/boost line.

There are different sizes. I dont know what bc you have but if i were you i would take it into autozone or another autoparts store and look at the hoses they have. Just connect the hose and make sure you get a good snug fit. I would also zip tie the ends for a little more security. 4mm or 3/16" I think are the most common sizes.
