Recently my charcoal canister rusted off my car completely. The wires are still connected but the canister itself drags. What is the suggested action to take on it? Should I buy a new one? Can it be bolted on? Or is there some form of adhesive I can use to reconnect it?

 

If the bolt studs are still intact and threads are not damaged you could probably create some type of brace to hold the canister in place, easiest thing though would be to go buy a charcoal canister off a pull a part focus, look for front end damage when picking a vehicle to remove this from.

 

I would use heavy tie wraps and resecure the cannister.

 

If possible, you might be able to secure it to a brace/bracket with a few hose clamps (various sizes)that might do the job.
