1st Gen R53 Cooper S Need help!...where does this vacuum line connect?

Hopefully someone with an R53 can help...I am finishing up a major service / modification project on my 2004 MCS...in the process I have ended up with a vacuum line that I cannot figure out where to connect. It is the "soft" line that is connected at the right (Passenger) end of the intake manifold...on the inside facing the engine block. Line is about 8-10" long, and has a right angle press on connector on the free end. I left this attached to the intake manifold when I took things apart, so I know that is belongs on the intake manifold....but where does it connect to on the free end?...there does not appear to be a waiting receptacle for it.

In the photos below you can see the line hanging freely...the line has a natural "set" that seems to show it ending up in this position...but as I say I don't have anything there to connect it to...or have I hooked up something incorrectly?

Any assistance would be greatly appreciated...I pulled nearly everything apart in the engine compartment except the short block and transmission....all has gone back together fine save this one lone vacuum line!

Images of vacuum line

Here are the images in case some have difficulty with the link:

 

Dave:
Thanks for the images including your detailed outline of the part. As it turns out that was the same connector that threw me off as I was reconnecting things...that connection comes from one of the several rigid vacuum lines that run on the right hand (passenger) side of the engine compartment....but your photos, sketch and comment about the fuel rail was enough to change my thinking and I realized I might be looking at this offending line upside down...when I considered that, the solution became immediately apparent and the line I am trying to connect runs from the right hand side of the intake manifold (where it is currently connected) over to the center of the fuel rail where it connects to a metal male barb fitting on the bottom of the fuel pressure regulater (#13 in the image below)...it will fit perfectly! (as soon as I can figure out how to route it over there without removing the supercharger again!)...should be possible...I'll just take a break now for dinner and then go fresh into it later on this evening....
Thanks again for your help...I know I would have looked at this for hours more without your helpful comments guiding me in the right direction.
Best Regards,
Cliff

 

Follow up note;
I did get the vacuum line properly reconnected. Interestingly enough there was not enough room between the S/C horn and the intake manifold to pass the 1/8" line...I had to loosen the supercharger, alternator, and belt tensioner...then a crow bar wedged between gave just enough room to get the line into position...from there an easy press on.

Wish I had labeled that line!....I did label most things as I was pulling it apart....but it's always the one you forget that causes the trouble, right?!?

So I'm back on track....this coming weekend should see much of the front end back together....still plenty of time before MOTD....

Only about 1/3rd of the front brake pads left, so I'll take the opportunity to swap out for new pads while the rotors are so accessible...that way I can avoid going through the wear sensors and having to replace those as well....

Still trying to decide if I should install the Milltek exhaust or just let the muffler shop do it...The new header is all installed and bolted up to the old exhaust. I have all new hangers, and have loosened the nuts, so other than the aggravation of crawling under the car and being a dirty job, I have no excuse for not doing it myself...the money I'd save would pay for another goodie for the car....

 

Dave:
RE: the Milltek.....yep, that's what I figure, it appears pretty easy, nothing to weld, just a couple of pieces, and I have all new hardware....of course history tells me this is when I should run, as these sorts of "easy jobs" always seem to turn out taking forever in the end!...LOL

Joker:
Thanks for your comments, although as Metalman mentioned mine is a Gen1 and the vacuum lines are different....I did sort out the issue, so all OK now.
