Not unless YO started recently. They were unavailable until CARS had them remade say within the last year.
If you are talking about the hose from the valve cover to the air cleaner, I got one from Year One last month.
I just used a regular piece of 3/8" fuel line. The bends aren't that radical. It works fine. Now if you want the moulded hose, you'll have to go with CARS
Since he said "PVC hose"I believe he is speaking of the formed hose from the front of the carb to the valve in the back of the intake.
Yup, that's what I was thinking too. The other hose is called the breather hose, and cars does sell them. I see them all the time when at the Nats. Cars always brings a bunch of them, different ones for the 400, and the 455.
I used fuel line too but I ran copper tube inside the hose where the bends are, makes tighter bends (looks better) and keeps it from crimping.
