GM parts listing worthless, need help finding hose

Ok, as a continuation of the help thread from yesterday, I need help figuring out a part number and name.

Specifically, the TB just before it bolts to the Supercharger has a vaccumm nipple that is about 1/4"od. There is a molded rubber hose connected to it, that then connects to a molded plastic hose that goes over the SC.

That rubber hose is cracked. I cant just replace it with another rubber hose as it has two different sized openings.

Went to the dealership today just to see if they carried something like that in stock. They couldnt even find the part on their engine diagram blowup parts listing.

Anyone know this part? Is it the SC bypass hose?

No. One line runs to the EVAP canister purge solenoid (and is how the gas fumes get cycled into your intake). The other runs to the FPR and supplies the vacuum to the diaphragm. I'll contact my parts guy and see if he has it. My GM SI service manual doesn't have part numbers, I don't think. I'll look anyway.
 
That one breaks a lot on our top swaps. The rubber just gets brittle, and you end up breaking it 80% of the time.
 
Wow, you guys are fast. lol

Does it look like this for that part number?

Why? You're just wasting the gasoline in your tank that evaporates to fumes. That's what the EVAP system does is reclaim those fumes and use them.
