It looks like you have a remanufactured canister. My vacuum lines go a little differently. My small line on my valve goes to my throttle body.

After looking at numerous diagrams my best bet it to follow the '86 tpi one and tie it in to the line that goes from behind engine (egr solenoid) if I recall to under throttle body.
