CDR Valve Hose?

I am needing info on the hose that connects to the bottom side of the CDR valve. I have an 84 6.2 and it has the CV870 valve. Not sure if it is available at the dealer, parts store or anywhere for that matter. Here is a pic of mine. I was going to take my CDR apart to clean it if not replace it when I saw this hose. Looks like someone has tried to repair it before. I don't want to mess with it until I get a new hose in fear of it breaking the hose when I take the valve off. Any part numbers and where to buy one would be appreciated if it can still be bought.
