How do I get to this hard to reach vacuum line

In replacing some of my broken vacuum lines I found another one under the sensor plate at the back of the engine. It's under the passenger side of the plate, connected to a t-connector, and goes down the back of the engine. I can't see where it's connected. Has anyone ever replaced this hose? What other than the throttle assembly to do I need to remove to get to it. I don't just want to yank it out and not be able to get a new hose plugged in.
In this diagram for the 2.8, it's the hose just to the right of #14, I think, before it splits between the intake manifold and the fuel pressure regulator (#13).
Any help is appreciated. TIA

^^ x2. Very important that you replace the one going to the Vacuum reservoir. A note about the intake manifold switch over valve/actuator: be super careful removing the vacuum line, the nipple can be very brittle and break easily. Also, be careful what you touch. I dropped a 1/4 socket wrench on the plastic rod that connects the actuator to the intake manifold and it snapped in half.

I know for sure one end, the top end, goes into a T-connection just under the sensor plate on the passenger side. It goes straight down from there to a spot I can't see or get to. I tried using a mirror but couldn't make out where it's connected. I can't get my hand down in there to feel where it ends either.
Mine broke. Luckily I could see the lower broken piece so I rigged it by sticking a spray can straw inside the broken ends and used RTV gasket sealer to band-aid the leak. I have new vacuum hose but just can't get to the other end of the broken hose in the back of the engine.
I think it's the section of hose in the diagram in my link in a previous post just to the right of #14 before the split between the fuel pressure reg and the intake manifold. But I just can't see or feel the other end. [Update: I think I'm wrong. I believe I've been looking at the diagram for the 12v 2.8, not the 30v which is what I have. If you look at the VW Passat 2.8L (rear view) diagram here, I think it's the hose that goes down from #4]
How to I get down there without pulling the motor? I'll try to get a pic up asap. Don't have a digital camera right now and my phone won't let me pull pics off it.
