What is eactly is this

[CRUZE 418]

What eactly is this, and what does it do? Fancy fuel tank vent? Parts available? Just clean the bottom filter and go with it? The foam rubber on the inside doesn't look all that great.

Looks like a charcoal canister.

Charcoal cannister.
Google explains better than I could:

Canister for emission. I believe the idea was to trap evaporate gases and reburn them.

Toss it. if the thermo valves dont work its just dead weight and ugly vacuum hoses to the fender.

Keep it if you want to keep gas fumes out of a house garage in hot climate.

My intention was to leave this car pretty much stock. Just bought it, the engine is hemorrhaging oil, and the more that I go into it the more it needs. Car was repainted and does not match the B5 Blue, the engine bay needs to be repainted. So I am going to just go over everything under the hood. I guess as long as it sorta works and doesn't cause any issues, I will just run it.
Thanks again everyone!

Check the lines to the tank; they collect water and rust up solid and pretty much nullify the canister.

 

[CRUZE 418]

Yeah, when I get to the fuel system, will probably end up replacing everything, except the sending unit!
Thanks AJ

i added one to my 71 since it didnt have one

it does prevent the garage from smelling like raw fuel

Charcoal Canister?

For the ones where the carb's bowl vent is connected, here's what happens when the cannister's top filters fail, and the connection to the bowl stays open with engine running.
