I'm thinking that the vapors or over-fill or splash from a full tank go into the canister and get relieved into this tank?
Who knows what is really going on here? Is there a better way to vent fumes and overflow than the stock system?
Thanks for considering and replying.

You are correct in your assumption that the smaller hose and vapor/overfill go into the "grayish" tank behind the headlight. However, there should be a hose that
exits that tank which then leads to the charcoal canister from which the fumes are then purged by engine generated air pressure into the intake manifold. I'm not sure where the canister is on your car--either in the engine compartment between the engine and firewall, or in the left rear wheel well. Check to see if it's still there and the hoses are connected.
Is there a better way? Possibly, but this system does work if all components are intact.
