Hello, I just got the tranny and engine into my '86 blazer. I have about 90% of everything hooked up. But behind the carb there is a T valve/fitting one of the vaccum hoses that run from that goes down to the tranny. But where does the smaller one go? I think on the old engine that was in the truck ran to the carb. But in my '85 there was a small tube the ran from the fire wall and hooked up to it.
