Power Brake vacuum line to engine connection
All: Looking for any insight anyone might have on where the vacuum line for the power brake booster connects to the intake manifold on an 03 Base Boxster.
I've clearly got a monster vacuum leak at the rear end of the car, and no power brakes, which all happened at some point during my drive to work this morning.
I'm hoping that the vacuum line just popped off (likely a fantasy, but what the heck) and I can snap it back on fairly readily.
Cross posting this to a bunch of places, so you may see the same question more than once...
Thanks in advance!

So, once you take off the engine cover, the location is blindingly obvious! And, it’s where the break is.
FYI, front of the intake manifold, just to the left of the power steering pump.

Following up to myself here.
If you need to do this job, removing the LR wheel and the plastic fender liner will help.
Two people will be required, and threading the new line in from the top appears to be the correct solution (we tried feeding it in from below, to no avail).
Oh, and cursing will be a mandatory part of the project.
