Charcoal Canister, is it OK?

[Busted Knuckles]

I started smelling raw gas when stuck in traffic this week. It was bad enough, I was starting to get headaches. This weekend, I found the problem. For some time, before I got the car, the purge line for the charcoal canister was put on the wrong port, the air bleed port for the EGR. This port had no vacuum, so the canister was not purging at all. It was this way for at least 2-1/2 years!

I swapped the lines back to the way they are supposed to go, and everything tests out fine. The gas smell is greatly reduced. However, since the canister is probably completely saturated, can the purge clean this out, or do I need to replace the canister? So far, I haven't been able to find a model-specific canister.

This is my '88 Supra , N/A, 5-speed.

Thanks.
