I blew cigarette smoke in mine to see if it was cracked, sure enough, the smoke started coming out of it along the firewall. It got chafed rubbing against the firewall and was leaking. Cut in half, slide a piece of rubber hose over and seal. It fixed the leak and should take a lot longer to rub through to make it leaked again...
You shouldn't be afraid of using rubber hose, it would probably do better, I have to take great care moving my stock hoses around, they are really brittle from all the underhood heat. Just get it in black color and it would look stock.

Anybody can take advice if it doesn't interfere with their plan.
