Default EVAP leak..

Does anyone know where the EVAP canister is? Its probably right in front of me, on my other cars it is usually a big box. I have a PO440 Check engine light. I bought a new gas cap, but it is still there after clearing it. I know some of my vacuum lines are iffy, the connectors are old and the vacuum line that disappears underneath the air box, I cant check if it is connected because I dont know where it goes to. Any suggestions? Very much appreciated!!

Did you check to see if the cannister itself isn't cracked?

The canister is A-OK I think it is fixed, I replaced every single vacuum connector/joint and I removed some rust I had on the filler neck for the cap and the light went away! Must be this site giving me good luck! Also changed the front window motor in 15 minutes! Solved my own problem, Good cars these are !
