The canister has two vacuum lines on top of it. Under normal driving, the vacuum pulls the vapors out of the tank through the hardline that runs out the bottom of the canister.

Fuel vapors are dirty, just like crankcase blowby or the remnants that come out of the PCV valve, combined together and drawn into the intake it all creates sludge. My engine does not have any of this routed back in anymore, last time I pulled the intake manifold it off it was as clean as it was a year ago.

Yud- I've owned 240s for 11 years now.
