I wondered the same thing about mine on my 75. The canister is a sealed unit so I guess if the charcoal is whooped one has to buy a new one the filter was the only thing I could get to. I checked corvette central for the tips and could find nothing under vapor or cannister are they calling it something else
Redwoman said: How do I replace the charcoal and the filters in the vapor canister on 1980 corvette. I tested all the valves and lines and everything is working properly.
So I just come across a great piece on rebuilding it shows how he opened up the canister and resealed it with jb weld where the bands hold it on the car, and apparently bought the charcoal at a pet store which is used to keep tanks clean. So there is one idea
Vette(s): 1980 loaded red on red. 68,000 original miles. Second owner. Well documented with all original paperwork.

I removed filter from bottom of canister and cut half of the plastic grille out.
I bought charcoal from ocean of pets. Made filters for top and bottom of canister. Reassembled and glued the bottom back on.
