Movement in the brake booster vacuum line at intake manifold

[pillow]

Here you can see the plastic connector (50, 40 and 30) at the intake manifold end, seems this is a fairly common way MB use to connect the brake booster vacuum line to their intake manifolds.

Basically I have some play in my vacuum line here and I'm just wondering if there should be some movement in the vacuum line. Please see the video:

Does it hiss?

Not that I can hear. It's right at the rear centre of the engine so not the easiest place to listen.

When the engine is at tickover it becomes very difficult to pull it (as you can see in the video it is minimal effort to move it with the engine off).

I'm wondering if when under boost, the pressurised air in the manifold might push it outward and leak out from here (if it is not supposed to move as in the video).

If it is a problem it can't be too bad because it isn't throwing any codes but I would like to put it right if it is wrong especially considering the low cost of the parts.

There is nothing wrong. Some movement there is normal. It isn’t leaking, I’d leave it alone and worry about something else
