unfortunately for me that is exactly the hose i am having a problem with.Mine must have been worked on before i got it because i see the tape on the two vacuum lines but the heater hose doesn't seem to be taped to then anymore. One of the vacuum hoses shows some signs of rubbing also so i wrapped it and tied it away from the connector that caused me the problem with the heater hose.
