Vacuum Leak? Help Please!

So,

There is a little black connector piece on the left side (looking at the engine) that appears to have 3 vacuum lines plug into it. I have a line that does not have a home. It is not the line that plugs into the intake manifold. I seem to be at a loss.

Does anyone have a schematics for the hoses and lines that I would be able to view to try and eliminate the ones that I know where they go?

I know I am kind of giving a broad description, but I will post pics later once I can get a picture of what I am talking about.

Thanks everyone!

Correct,

They are hard plastic with a rubber end that gets attached somewhere. Like I said, I will post pics when I get a chance to run out into the garage. (Tonight most likely)

gray one with rubber end goes to pcv. curvy hard line goes to the bottom of canister purge valve. hard line with 90 degree angle goes to the top of the canister purge valve. the line smaller line that runs next to the valve cover gets attached to the T-adapter that that attaches to line going to the top of the canister purge valve. lastly, on that side there is the hose that runs from the intake manifold to the fuel pressure regulator

Hmmm...

I'm wondering if it is the one that get's connected to the t-adapter. I do recall having to deal with this when installing the boost gauge.

Thanks for the input. Does anyone have a picture of where all these would get plugged into?

I'll post pics tonight, I promise!

Ok guys,

Thank you for bearing with me...

The first picture is the line itself that is in question. The second picture I took, because it appears that perhaps something is broken off in there? Thoughts!?

Thanks!

If you're talking about the tube that connects to the intake manifold, I don't think this is it.

Let's keep spit balling here!

ok. i just looked at my car...

you see the fuel regulator there in that pic? its the round dealy with the tube that hooks off to the Right. follow That tube. about 4 inches in, there should be a 3 way T piece, under the SC horn. the tube that your holding fits to the Bottom of that 3 way T: one end should go to the round deal, the other shoots off towards the driver side, and the tube you have fits to the T!

First, I would like to thank you for posting the pictures! THAT IS AWESOME!

Second, I'm wondering if mine was disconnected when installing my boost gauge and never re-attached? I will have to look and see where that T adapter all comes together and see if I have an open spot!

The MINI is at my buddy's garage for storage for the winter, so I wont be able to get there until this weekend :(

So I was looking at what you were talking about on my car and found this line very close to it disconnected. Any idea what it's for and if it should be hooked up? I'm assuming yes... pic/diagram attached.

Well whatever it is it keeps popping off and is the source of why my car's been running like crap (just posted a thread about the same time I saw yours in fact).

Many thanks to your problem for helping me find mine though. Sorry to hijack your thread a bit but many thanks man.

Hey! Happy to help! Maybe you'll return the favor one day. This is what's great about NAM, it's like a big Mini family!

Try a zip tie around the tube. I'd say glue, but you don't want any inside the line.

Yeah, ziptie is what I used on mine when I tee'd off that line for my boost gauge. I'm honestly not sure what it feeds. A few years ago, I noticed a leak (got so bad my boost gauge was reading no boost of vac. The tee I put in self destructed. The car still ran fine. My scangauge was reading the MAP sensor and it was reading proper vacuum.

Update:

Thanks to astroBlackMetallicMini, I found where my missing line gets plugged into. It is the vacuum line that comes all the way from the throttle body and clips into the bottom of the canister purge valve. My missing line get's plugged into the "t-adapter" part of the line coming from the throttle body.

Here's the crappy part. As shown in my picture, it actually snapped off the line and the plastic piece is lodged in the vacuum line. So, I need to replace the line from the throttle body, and hpefully be able to dig out the plastic reminants in the adapter.

Thanks for your help everyone!

Iam fairly confident that the port that you're referring to in the picture is for the boost. I would take a picture of mine for you, but I have a boost gauge installed and forgot where the OEM line would come in from.
