Can anyone provide a link to, or spell out, instructions on R&R the charcoal canister/ filter for the EGR system on my '94 C280?

Is this the same canister for the fuel tank overflow?

Lately the CEL has shown a code for the purge valve which I found to have a fine black grainular substance in it. I can only think that the charcoal filter/ canister has ruptured some how and is getting junk into the line. The purge valve itself seems to stop the charcoal from getting any further in the system.

Thank you for the help!!
