What does this do? :)

Hello OpelGT forum,

I feel so stupid asking this, but I have no clue what a certain part on my GT should or is doing. I took a picture of it, attached below. Could you guys help me out

2 attachments, 1 detail of my actual part, 1 of a mint engine, having the part as well, to give you some reference.

Found another closeup on the mint engine:

Its the charcoal canister, it is an emissions component. Luckly for me in CA I am able to throw it away.

Thanks for the quick response. Could you explain how that would work? Can't imagine it filtering the exhaust? aaaah

**edit, ok nevermind I figured it out , thanks for the info.

It is there to trap raw fuel vapors that exit the carburetor, the fuel filter, and the fuel tank while the car is sitting. Then when the engine is working, those vapors are somehow rerouted to the intake, where they are burnt. I say somehow because my euro-spec car does not have charcoal canister, so I am not familiar with its "plumbing"!

In addition to trapping fuel vapors coming off your float bowl and fuel tank, it also serves as a vent for those. Pre-emission cars just vented these fumes to the atmosphere. Why is a vent needed at all? For one thing, as you take fuel out of the float bowl or fuel tank, you have to replace it with air or else you create a vacuum. That would inhibit the flow of fuel, or collapse your fuel tank like a beer can. Also, pressure from heat after shutdown could push fuel into the engine, causing flooding. The vent relieves that pressure.

If you are using a Weber carb without a float bowl vent connection, you still need to vent the fuel tank, so don't cap off the line that goes towards the back of the car. I would recommend leaving the canister alone. It's probably best to cap off the large connection at the canister and connect the purge line to the air cleaner or some other partial vacuum point somehow, if you're environmentally conscious. The vapor canister, while an emission device, doesn't hamper performance.

This is the third time I have attempted to post here - each time my internet connection crashes - Charter Communications is the devil!!!

I found this article describing the plumbing for the gas vapor venting, but this is the first time to see a picture of the physical location for the vapor canister - so thanks for the photos Breen!!!

If the foam filter material rots and turns to powder, like mine did- you can use standard lawn mower air filter foam to replace it.
