hey everybody, i was looking the web the other day and i'm interested in getting some color vacuum lines but i dont know what size they are.
the lines that i wanna replace are: IM to BOV, FPR to IM and Fuel Rail.
and i might replace the windshiel wiper hose.
anyone know the size?

edit: i meant size like in diameter.
