Welcome. I will try my best to help you and in order to do that, I need you to describe as best you can because I only know as much about your problem as you have told me in your post, so my answer will be based on what you have posted. Please feel free to reply as needed.
Is this the carbon canister?
If so, then you need to remove the fuel tank shield to get at it.
Important: Do not pry against the surface of the evaporative emissions canister. This could damage the canister.
