i think they had different ones for different years as well as different ones for different states. in new york we have the "california" cars if they are sold new here. mine is different than all those. i have one tb connector that two lines come out of for the purge valve and fpr, my vent valve is on top of the canister which is on the pcm. its has a metal line from it to the purge valve. well until it started leaking

Makes sense, I thought I seen some pics where it looked like there was only one port on the throttle body, I was not sure though.
If your purge valve metal line is still leaking, and you need an easy fix for it, get some Rescue Tape, that stuff works great.

i just ran all new rubber stuff, its not very expensive
