I bought an autometer boost gauge n have a new line n a pack of tees from summit racing close to my house n I don't know how to get clear vacuum line to connect to the tee?! Some help please. The line will fit inside a tee but isn't air tight, what to do. Thanks. I have 2000 a4 1.8t quattro

 

Inside the tee? On mine, the tee fitting had small nipples on it that the vac line slid onto. Can you take a pic of what you've got?

 

It won't let me upload from iPhone. I'll have to go back, I don't think I have right tees, these r just for rubber hoses I think
