Hey, I could really use some help here. I’m trying to find an exact vacuum hose that connects to the upper plenum and the EVAP cannister purge volume control solenoid valve so I can just replace it. I posted a picture too and my car is a 2004 350z

 

Any hose of that diameter will work … don’t overthink it

 

^^^ Agreed, just take the hose into an Ace Hardware or True Value (or big box store) and ask for a match. Gl!

 

I think you just have to replace it

 

As stated just replace the hose with one from a parts store or hardware store, if you don’t want to bring the hose with you, just measure the length and go. You can remove the old hose from your intake and use a wrench to measure the nipple, just slide the open end over the nipple, it looks like a 3/8” or 10mm to me.
