Alright, I'm in the middle of desmogging my 81 Fj60 and I've read the desmog threads until my eyes started bleeding and I think I understand everything and what to hook up and what to junk. But when I got to the High Altitude compensator, the bottom hose was just dangling and not hooked up to anything, so I put the white cap on it just for fun. The only thing I haven't been able to find is where this is supposed to go, or if it's even supposed to be hooked up at all. I'm in East Idaho so I definately will be needing it. Thanks.
