This hose is developing a crack but I don't know what the hose does or is called...

I am getting ready to put new plugs into my 2002 SR5 and during my preps, I saw a problem with this hose. Not only does it have a crack/tear in it at the mounting point, but is also does not have a clamp. Here's a close up of the hose:

Here is the location in the engine bay from the passenger side:

Sorry for the crappy Photoshop work, not easy to pick a color that is legible against the engine background. :D

Any idea what this hose is called and/or does?

I've never replaced a hose before, so do you have any advise on how to go about it? Do I just walk into auto parts shop with the hose and ask them to match it or what?

Any advice appreciated in advance!

Thats about the easiest one to replace. Yes, it just slips on. I don't believe that hose has a clamp.

Bring the hose to the local auto parts place and ask for the same. Sells by the foot. Remember the ID (inside diameter) is the most important in this case. You need vacuum hose, but I imagine fuel hose will work.

In the interim before buying another hose, you can likely take a snips (even scissors) to remove the cracked portion and replace.

Hope this helps!

Thanks for the quick reply!

I assume there will be some correlation between the ID and the OD? Not sure I can get an ID with the calipers I have...or will the store "just know" and be able to match it up?
 
I'd pull the hose off the air box, cut it just past the split with a utility knife and put it back on. There should be enough slack for that 1/2" of loss
 
That hose is connected to Fuel pressure regulator and it is open to 1 atmospheric air pressure, so there is no need for a hose clamp.
 
OK, this morning I removed the hose and decided to measure the "ports" it was connected to with my calipers to help determine the ID and buy a replacement. I could trim the existing hose, but for a couple of bucks and the ease of the job, I figured I should just swap it out.

The end that attaches to the airbox is 0.360" while the side that attaches to the engine is 0.280" I measured twice just to make sure and was within a couple of thou each time.

Would a 9/32" stretch to fit the larger end? Sorry, I am not sure how elastic these things are!
 
Just found a similar thread from 2017, linked here for those who follow: 02 sr5 vacuum line question

Still not sure what size to buy, so I'll hit up the parts counter this week to pick one up, then post part data to close this out.

EDIT: Here's another thread about it on Yotatech: 3.4 with no Fuel Pressure Regulator vacuum - YotaTech Forums

Apparently not a big deal, but as an amateur mechanic wanna be, I like to fix things like this. :D

RE-EDIT: I think this thread answers the question: Anyone know part # for this hose?

Toyota Part #: 17343-62110

Here is the shot from the Toyota service manual, page EM-71 in my version.

You are on the right track!

The auto parts place will be able to identify the right hose if you hand them the old hose.

If you really feel adventurous then remove the airbox and bring it to the parts counter just to be sure it fits.

As others have already said, just cut 1/2" from the end and re-attach. I did that once and the same hose is still in use after 21+ years and 511,000 miles.
