It is held in the boost with a rubber grommet. I rock the fitting around a bit and spray it with silicone and gently remove it. That grommet is around $20 so try not to tear it.
Usually when these fail it is visible that the hose is cracked. You could remove it at the booster and check for vacuum with the motor running, then check for vacuum at the pump. The bad part about that way is then you're stuck with an unusable car or reinstalling a bad part that probably is now in worse condition after being removed.
They all have the small fitting on them. This is the source for the vacuum system that operates things like the VNT actuator on the turbo, EGR valves and such.
Does that twist of pop off the brake booster? That is the vacuum line that connects to the brake booster right.

This would have been useful if you also showed where those lines are in the vehicle.
They all run from the vacuum pump on the end of the motor to the brake booster.
Can you test them to know if they are bad on the car and it’s not the pump itself?

2nd one from the left, what does the very short tube sticking out of the saucer do? Is there a hose that goes on that?
