Question : What is this, and how can I keep it from unhooking

[PerfectCreature]

Just had the new UIM placed on, made a huge difference, everything is smooth and gradual.
My only issue is that when they put it back on, and think they may have run the wires in an odd way to cause this?
How can I keep it from unhooking?
I have the clamp to hold the "L" in place to the intake, but the tube keep unhooking from the "L".
It throws a Service Engine Soon light, not sure if it is something that is serious, or something that if it unhooks, I simply go about my business and hook it back again when I have time.

Need to remove the tension, the tube should rest in place.

What does it run to? What code is thrown when it detaches? If it is a simple vacuum line, you could just replace the line. If it is a hard plastic line, try securing the line and the "L".

I looked in my Haynes Manual, and I think it is the breather for the engine to get fresh air, or it is a tube that recycles air back into the engine. It is one of those two.
It is unforunatley a hard plastic line, and it is about $22 to get a replacement, so I think I figured out a way to secure the line.
I got one of those bypass stoppers that fits over the "L" and I plan to cut a hole on the otherside of the stopper to fit on the plastic hose, then slide that back and put a quick connect clap on, bend down the quick connect tabs just a little, and the slide the stopper up and secure it to the "L" with a clasp.
This way, if the hose does slide out a bit, it should still have the seal.
Any objections?
Any other ideas?
Thanks.

Heat shrink tubing might work well and look clean. The type used on wires, if you can find one large enough that fits snug it will shrink down tight with indirect heat (lighter flame).

I found them at advanced auto parts and radio shack. Sure there are more places.....


The tube is probably the fresh air feed for crank case ventilation. If you have a MAF, that will make the car run a little lean from unmetered air entering the system. This way, the car can ventilate the crankcase with air that was measured so it always knows exactly how much air is flowing.


Are you boosting? I see the telling silicon coupler. If so, you may have to change up the PCV system so as to not push pressure into the crank case.

That's a good idea, I used to have a bunch of heat shrink tubing, though I am not sure if I have any left....
I will have to check.

If heat shrink doesn't work, vacuum hose with an inner diameter a tad bit smaller then the outer diameter of the hard plastic tube might work. If you get a good tight fit it should hold.

I took your advice on the vacuum hose, I found one that had a really tight fit over the "L" it streched a bit, and then had a semi-tight fit over the other one. Not enough to cause stretching. Attached and it made a difference.
Had code erased at local shop. Was a P0107 or something....it was a code that said the car was running lean.
Thanks for the help.
