Good evening Acurazine. I've recently replaced my purge solenoid valve on my UA7 that is located just behind the throttle body. After finishing the installation, I noticed that there was just a loose vacuum tube dangling just below it next to a vacuum solenoid. I manually traced the tubing and towards the back, the tubing t's off into two other tubes, which I am suspecting is the lines for the engine mounts. However I cannot seem to find where this tube goes. I have attached a photo of the suspecting tube circled in red. Keep in mind this is taken from above the engine, directly behind and below the throttle body. What helms manual should I look at to find where this piece goes to?
I've also attached a diagram of the vacuum tubes located nearby, but this diagram doesn't really give an exact location of the tubing that I'd suspect is the culprit tube. I believe the T that I manually felt was part #29, and part #63 seems like it might be that tube, but it doesn't show where it goes to.

That's because you are using the 'diagram' for the manual transmission TL-S.
Your profile indicates that you have an automatic transmission.
If you reference the link below, for the AT, it looks like #45 might be the vacuum tube in question which would attach to #26 electronic control mount pipe?

It would seem you are correct. I failed to mention early on mine is AT, but I didn’t even notice until after. But this makes a lot of sense now. I’ll have to get under the car and see where that tubing went. It is possible a portion of it might still be there, but if not, then I’ll have to get a new tubing for the front mount. I did have my transmission serviced early on into the year so I bet the technician didn’t even bother to notify me or just didn’t want to fix his mistake. I’ll report back on my findings and then go about buying the correct tubing and bolts. From my understanding on the helms manual, this tubing shouldn’t affect engine performance as far as a vacuum leak is concerned since an external solenoid behind the intake manifold controls the vacuum for the mounts.
Good afternoon members. Sorry for a late update, but I finally took some time to inspect what specific parts were missing, and it's everything from part #45 and going to the front engine mount provided by Zeta's link. They cut the hose and basically never re-installed the tubing and pipe. After reviewing, I ordered parts number #24, #26, and and two of #49. Local Acura dealership wanted nearly $180 for those parts LOL. Managed to buy online with S+H for only $54. So I'm looking forward to getting these soon and getting the front mount back to normal. It might also fix a bit of the vibration I'd have while accelerating.
Good evening. I finally got the parts needed, and installed the new tubing along with the lower metallic tubing that goes to the front engine mount. While I was in the bay, I further inspected the rear engine mount and found the nipple to the rear mount to be missing, and was broken into the tube that leads to it. Luckily I've purchased an OEM front and rear mount which should be arriving on Thursday. My only concern now is this clip, but I have no idea where it is suppose to go. I don't see any kind of bracket to attach it to, unless I am missing something. Where would this be attached to?
Good afternoon, I have returned to update the status on my vacuum repair/replacement. So firstly I’m glad I decided to replace the lines, because while down there I managed to replace my rear engine mount, which was completely shot. Happy to say that my front and rear engine mounts are back to OEM spec, and that there is no more vacuum leak. Below I’ve attached a photo of the rear mount. It was completely shot. Regarding the small mounting bracket on the front vacuum hose, I found that there is a “stay bracket” that helps supports the hose from wobbling. I have ordered that part and hopes it arrives soon. But that stay bracket is bolted to the upper part of the front engine mount.
