haha! That's funny. You know, I didn't ask where it was - under the hood probably. I don't think he told me, but the code on the receipt shows EMI500 - does that tell you anything? I saw that the guy working on it pulled that big thing off from the top of the engine but I really have no idea where the hose was. Seriously, if you really want to know, I'd be more than happy to call them tomorrow and find out.
