What Size T-fitting

[JOLTY TacoMan]

I recently purchased a Glowshift Tinted Series boost gauge from craigslist and it did not come with the T-fitting required to tap into a vacuum line. What size/type of T-fitting do I need and where can I buy it locally?

Hey there, When I was in your position, I took off the line I was going to T into, and took it to the local CarQuest. (napa/shucks/O'Reilly's/possibly wal-mart will also have them) and I compared the size of the hose to each T while it was in the package. The guys @ Carquest just let me find one that was close and open it/ try it in the store. They also make packages of T's with multiple sizes inside. Hope this helps.
