need pic of evaporative canister from TPI
Can someone please post me a pic of your Evaporative canister from a TPI set-up? My carb set-up does not have a purge solenoid and electrical connections on the canister itself. I want to know exactly what I am looking for when I go to the bone yard on Thursday morning.

Carbed versions used a Ported Vacuum source to signal the Canister Control Valve. Ported Vacuum is vacuum off idle. The port sits above the throttle plate so that there is no vacuum when idleing. The whole point was to prevent the canister from purging when at idle, due to the low volume of air.
On fuel injected cars, in uncommon to find ported vacuum because the ECM just used an electric solenoid. You can still use the carbed canister, just use an external purge solenoid on the "purge" line, and let the TPI computer control it.
