XC70 Vacuum leak/ smoke test

[sjk5539]

Hello,

My 2008 xc70 got a p0442 (small EVAP leak) code and I am trying to smoke test to see where the leak is.
However, I can't figure out which hoses are vacuum lines and where the purge solenoid is.
I think I can use this line (picture attached) that is connected to the coolant reservoir...

Does anyone know where to introduce smoke?

Cheers
