So I got my headers installed and my mechanic said that some of my vacuum lines got mushy so he took it out, and it came out behind the intake manifold and he said all I need is a y connector at the end of two lines that run side by side and goes to that y on the passenger side, but he said that its a rubber piece and he couldn't find anyone with one does anyone know where I can get one? And also I need the piece in the picture. Thanks for any help!
