Anyone know the part number for this piece? It's completely wrecked in my car, and probably the cause of my vacuum leak. It's not a regular hose; it is molded into a fitting at one end for the "purge tvs" It's the red hose in this diagram.

 

just go to gm parts and tell them what you have and what you want. even if someone had the pn it would of changed.

 

A regular hose (3/8" IIRC) will work fine. I have no idea why they made that molded end on it with the 2 hoses, it doesn't seem to be necessary for operation, it's probably just for mfg convenience. The TVS just has a regular hose barb type fitting on it.
