9er vacuum hose question

Hey all,

Recently took a trip, and part-way into said trip, some goofy stuff started to happen. The RPM's would surge, going from about 2 grand to 2300 and then 2500. When I got home, I started my search for a vacuum leak (as that's what I had it narrowed down to). What I found was the passenger side hose-boot-thingy that comes from the intake (on the keg, about halfway front-to-rear, and halfway up-down) and goes who knows where was disintegrating. I'll add pictures in just a few, but my question is this: Does anyone have a part number for this hose? I know it doesn't really do anyone any good without a picture of the hose, but I figured I'd post on the outside chance that someone knew what the hell I was talking about right off the bat and speak up. Uniblurb helped me out last time I had a hose issue (thank you sir! ) so maybe he can help one more time

Thanks in advance guys!
-Evan

Here are the pics, as promised:



Terminates at what looks like the charcoal box (?) or an evap canister? Not sure... It's right below and a little behind the passenger-side headlight.

Can't see your pics MTBlue since it says they've been moved or deleted. If you know where the hose starts/ends believe I'd just get the hose inside diameter and buy fuel or fuel injector hose of the same size/length to replace it. Normal vacuum line they sell now is not fuel resistance and why I mentioned going with a hose which is. Vacuum pulls gas fumes from the tank, filters them through the charcoal canister, then is pulled into the intake to be burned in the engine. Good luck!

Crap. Didn't mean to do that... I'm gonna try to get a hose elbow tomorrow morning when I make a run by O'Reilly Auto. That should get the job done... I hope haha

Thanks for the input!

YW and didn't know you were talking about maybe a pre-formed hose elbow. If it's a tight turning one sometimes you can just get one of those plastic 90 degree elbows and put a piece of fuel injector hose on each end. While the OE vacuum hose from the canister to the intake they used was somewhat fuel resistant they do tend to rot because of the caustic fuel fumes. Know I've had to replace them on most of my Jeeps. Good luck!
