Mystery Vacuum line
i recently had the engine out of my car and after the install I realized I forgot to connect this vacuum line. I remember disconnecting it. I can not for the life of me figure out where the hose is i connect it too. I have it plugged for now and still runs fine. No CEL.

Where does that hose go? That rigid hose is not there on mine and I don't think my connecting hose was rigid. If I remember right it was another rubber connector like the one with the screw in it in my picture and it had a straight butt type connector between the two of them. After the rubber connector, was a small diameter plastic hose. If i knew where it was routed too I could trace it backwards. Gas tank?

The vacuum pipe, as it is called (the part you reference), connects to the fuel rail at the intake manifold, then to another rigid vacuum line which snaps into the holder directly underneath the top (rigid) one in your picture, then runs parallel (to the top rigid line) down the firewall and back to the fuel tank.

It's the purge line from the charcoal vapor canister. The canister connects to the fuel tank to absorb hydrocarbon vapors. That line feed into the intake manifold to burn those vapors. The release of those vapors from the canister is controlled by a solenoid valve, called a purge solenoid. It's an important part of the emissions system.

Looks to be the Fuel Pressure Regulator Vacuum Line, which I believe connects the fuel pressure regulator to the intake manifold and the tank vent, #11 below - part number HERE.
Edit: So on this diagram, I think it connects into the fitting of the vacuum pipe (#4 - part number here) going back to the gas tank area or vapor canister. (As stated above).

Pelican Parts, I think you got it right. Part 3 in your second diagram is the purge solenoid hose which you can see in my initial picture. Why there is a constant flow vacuum hose (part 4) going back towards the fuel tank is beyond me......Do you know what it connects to back there?
I must have tucked it behind the heat shield or something when pulling the engine. I'll just have to dig for it!

I've been wrong before. Wouldn't be the first time. Hard to tell sometimes from a picture. Most engine intake manifolds will usually have 2 or 3 nipples: for PCV, evap purge and sometimes a separate one just as a vacuum input to other stuff (like fuel pressure reg.). I think the Mini tees off the purge line for that per Pelican's part diagram

I have that same rigid line with the cone fitting at the end of it. It is sitting on my intake, underneath the intercooler, on my R 53. It’s not connected to anything and I’m wondering where it goes.
I recently found that fuel pressure regulator vacuum hose broken at the 3 way connector under the inter cooler and I already reconnected that one. I’m still having issues throwing the P0340 code and having no power, and missing at lower RPMs with moderate to heavy throttle.

Check realoem.com for the best parts diagrams for these cars. I'm not too sure which rigid line you're talking about, there's quite a few.
Once you find out, let me know and post a picture. I might have one lying around I can get to you for whatever you can afford+$10 shipping to the continental US. Might be cheaper than buying it new.

Anybody know a good Mini mechanic in Southern California that won’t charge me for the diagnosis?

Most shops will give a free diagnosis if you ask nicely and have the part replaced there. I doubt any shop will diagnose for free and let you drive away without paying for their diagnosis time, though. MINI dealers charge $100 for a full diagnosis and inspection.
Alternatively, if you just want the part replaced, check yelp for your area. Search "european auto service" and go to a shop with 5 stars and 50+ reviews.
By the way, if you have the time to learn, front end service mode is a piece of cake after the first time. Won't take more than 15 minutes once you get it down. ModMINI has a great video on YouTube.
Dig deep, there is a wealth of knowledge on here. Once you're working on it, be methodical and work from one end of the system to the other. Don't be afraid to go to your friendly local dealership and ask the service department leads/common fixes. If you have the time/interest, you'll figure it out.
