Yes, you're right. I was just trying to make a point. The governor controls the bypass of the fumes. If the pressure is high enough the governor opens the passage for the fumes to bypass the turbo so that the turbo pressure does not increase any more.

That's right. It's the same vacuum pump but there are two outputs:
1. Low volume, high output for turbo,
2. High volume, low output for the servo
The hose diameters indicate that.
