i just got my 350 TPI in my 87 pontiac formula but have a problem. I have no idea were two line that come from the Vapor Canister goes, i have no open vacum opens and am lost on the correct place. Does andone got a diagram of all of the Emmisions/vacum line go?? i need help thanx.

 

The vac diagram should be on a sticker under the hood. I had the same question and just happend to look up and there it was. If not one of the canister lines runs over behind the over flow tank for the radiator, behind the alternator and connects to the right side of the throttle body. There should be two fittings on the right side of the TB. Upper goes to the PCV and lower goes to the canister.
