VOLVO 850R Auto Tracing Vacuum Pipes the White one?

Hi guys just going through everything now I wonder if anybody can help with correct connections of the White Pipes that seem to go into a valve Front right
Just checking that this is connected correctly...er...what is it? Could it be blocked
Cheers

As Lee has already said, the white pipe exiting the bottom of the picture is going to the dashboard boost gauge and the other white pipe runs to the fuel pressure regulator and the valve you mention that they are connected to is in fact known as the Vacuum Tree, hope this helps
