I had the same hose go out on me, the worst thing about it is that it comes coupled with two vacuum hoses and runs from the top left of the engine down to the heater core. The hose is also a larger diamater on one end than the other. Mine had rubbed through on a connector on the top of the intake and was leaking a lot. What i ended up doing was getting the correct size hose for the top connection and running it down to about 8 inches from the heater core where i got connected it to a piece of hose the correct size for the heater core by using a reducer. I can't remember what size hoses i needed but i think it was 5/8 on one end and 3/4 on the other. Oh and make sure to change the routing of the hose to miss the connector on top of the intake.
