I had a similar issue with the heater feed hose from the flange to the heater core on my B5.5 V6. I found a new hose for $43 and it took about 1 hour to replace. I had to spend 30 minutes just to get the hose off the flange after removing the clip. Not much room to work on a v6 as the hose is behind the firewall. Anyway a new hose is needed to make the repair.
