D16Y8 Intake Manifold identification help

I have a pinched vacuum line coming from my intake manifold. It goes underneath the fuel injectors/rail to a boot. I know I need to replace the piece I'm just not sure what the piece is... Ive attached this picture to help identify. By the way this is my first post, and I've only been a civic owner for about 2 weeks so all the help is appreciated.
