2007 Continental GT rough idling

This is the cutter. Any bending I did, I did by hand

So I looked under the hood pictures on @Stevieshutts
post , looks like the only line he connected to was #1 on my picture , what about #2 and #3 intake lines , do they remain untouched ?

So I removed the passenger side wheel well and it's different from Steve's picture , there is a manifold pressure sensor sitting on the vacuum line that's going from the engine bay to the back of the car.
Should I connect my bypass line before the sensor ?

Here is his picture:

It looks like it's working !
I haven't driven it yet , but rough idling is gone , pump doesn't activate with brake , no leaks , no CEL.
I've done it a shorter way though , instead of using a T and running a new line all the way around the subframe , I ran a new line directly from the pump to where the bulkhead hose connects through the steering rack cavity , connected a new line with a T and continued the new line to a passenger side wheel well through the steering rack cavity, connected a new line before the sensor , I used about 7 feet of the line , one T and two straight fittings.
That's it.
Driver's side connection to the pump
New line going to the engine bay
New line connection on the passenger side
T connection to where the bulkhead hose was

Nice work. I did a version of this mod myself and it's held up for almost 2 years so far. The only issue that I had/have was that with the bypass line fully connected, upon acceleration (and only acceleration, not braking) the vacuum pump would turn on very briefly.
Assuming that this was because my bypass line added more length to the system, I disconnected the part of the line that goes to the exhaust valves and the evap purge valve I believe. This solved my problem, although I do get a CEL every so often (500 miles? Not sure) for the purge value being inoperative. I'm not sure how to fix it yet.
Do you have no more vacuum pump noise, even under acceleration?

Thanks for your help !

If I'm reading this correctly, you ran a new line behind the steering rack, parallel to the original line? Mine is a bypass route that goes below the engine, then back up to the wheel well. I then capped off both ends of the old leaky line that ran behind the steering rack
