I recently purchased a 93 del sol with a D16z6 and it appears to have a leak coming from the bottom part of a black cylinder shaped piece on the firewall, the hoses coming off of it go to the throttle body and intake but i can't tell where the 3rd is going to. does anyone know what this part is called? Thanks in advance!

 

It's the evap charcoal canister. It's part of the fuel system.
