It took me over an hour today to get the lines unblocked from all of the charcoal pellets - I strongly recommend canister replacement as preventative maintenance, to avoid the fun I had today (and the expense of a new purge solenoid!)

So you think this more a time versus mileage thing as our cars are over 20 years old? I notice your car has 189K....WOW. I'll think I'll do this when I have the car up on the lift to replace the headers. Thanks again for sharing.

Hard to say, really... it's a non-wear item (no moving parts), so that leads me to believe it's more age related than mileage related, if I had to guess.

UPDATE: The Standard Motor Products canister is the OEM Rochester unit, with a GM part number on it. No reason to waste money on the Delco can.

My Standard Part Number PF 1031 canister came in from Rock Auto today it is also stamped Rochester on the top. Just FYI. Thanks for the tip again Andrew.

Okay, guys. Here we go again with the unique 90 MY stuff. I see that there is a different part number for the cannister (almost double the price), but the valve is the same as other years:

How much is it for 90?

Looks like it has the purge valve built into the top of the canister, unlike the 91 which has the purge valve in the tank, and the canister has no moving parts. Bummer.

Also, note there's a solenoid and a valve - solenoid under the plenum sometimes incorrectly gets called a valve.
