I have been searching for hours online to see what this line is called but I cannot figure it out. It needs to be replaced because it is broken. As far as I can tell, this line connects to a "T" connector which goes to vacuum lines for the HVAC/EGR? The line starts close to the firewall into a "box" that is covered by the aluminum foil looking thing. At least knowing the size of the hose would be amazing. Pls help! I have colored the line yellow so it is easier to tell which one it is.
