Wornout vacuum hose that drives CBV

Discovered that the rubber vacuum hose from the CBV to the intake manifold is in bad shape.

The other night when I floored the accelerator, the turbo kicked in and at about 4000rpm, the engine stumbled and rpm dropped to 1000 and came back again. Could this be the cause of the problem.


Do you know what is the size of the vacuum hose that I might need. Is there a standard size for all the various vacuum hoses in the car.
