The pipe that is stock on the upper hose of my K15 350cid is just aluminized pipe(exhaust tubing) I still have the original pipe in there and its just starting to show some signs of wear. Thats 34 years old. I have now opted to run a molded hose and had to sort through bout a dozen before I got one to fit, I think that the description was for a D****E but I wont tell anyone.
The lower hose that I finally searched for looks like it may also work in your spot. I can look up the no when I hit the shop tomm if you like. If your local parts store carries dayco I can also cross the Goodyear nos to Dayco.
