Hi, I found the general area of my vacuum leak under my hood where all the vacuum lines meet up. It seems when I push the orange line, the vaccume seals and the pump stops running. The elbow connector may be damaged. Whats the best way for me to fix this without braking anything more?

 

Also, does anyone know what the black vacuum line goes to? I accidently broke that elbow connector completly, but it dosent seem to change anything or make the vacuum pump run any more than normal.
