Not sure on the first one.
The second larger hose looks like the vacuum hose that goes from intake manifold to the vacuum brake assist mounted between the firewall and brake master cylinder. Make sure none of the hoses have any leaks. I just replaced the brake vacuum line on my 01 V70 Yesterday. The valve shown is a one way valve to allow suction only 1 way.

The first hose goes down to a pressure regulator down on the bottom near the subframe on the passenger side, the metal tube runs along the coolant tube then exits to another length of vacuum line to the regulator. The second tube with the one way valve is running correctly and does go to the intake tube
