Charcoal canisters are part of the EVAP system and are used to absorb/filter petrol fumes from the tank that vent out during expansion/contraction of the air inside. The air is dumped back into the system through the throttle body.

I think there meant to be replaced at 30k miles, but I don't think anyone does.

Maybe someone could clarify and explain a bit better than me, but I hope this helps you.

I imagine it should be the same for a hatch as a coupe of the same year. If you look just to the right of your battery, you will see a can (usually black) hanging on the firewall. It looks similar to large oil filter. It should have 2 metal lines running to it. This is your charcoal filter. They are about $20-$25 at your parts store. Also, I don't believe it is an evaporation cannister. Rather than an inline fuel filter, the fuel line from the tank connects to the charcoal cannister and then the line from the cannister runs to the the fuel rail. This cleans the fuel of impuraties as an inline filter would. It does not collect the vapors as you will find out when you remove the lines and fuel drips out.

The purpose of the charcoal canister is to collect and store fuel vapor. If you have fuel in the cannister then you are likely overfilling your gas tank and it's running into the charcoal vapor canister.

You dont have to replace teh EVAP canister. Like many have said its just a device that absorbs liquid/vapor gasoline. The container itself isnt even enclosed. There are small holes in teh bottom. To allow a vaccum action when the car is turned on.

When an automobile is not in use, a charcoal canister stores gasoline vapors from the engine and the fuel tank. Later, when the engine is running, these vapors flow back into the engine for the purpose of combustion.

Damn, I feel like an ass now. It's crazy because all the auto parts stores list that same item as a fuel filter. Now if someone could describe where the fuel filter is located......

since your from STL i can help you there. Go to south city, there is a bar named peppers. Go in and drink alot, it all goes away

 

[rickles8099]

even with the turbo??

to do that i had to change back to stock fuel injectors, stock ecu, and disconnect a chargepipe.

and then it passed with flying colors

but the charcoal canister was still off of the car.

i would have love to have seen the look on the guys face if you failed, and he poped the hood to see a disconnected turbo sitting there

the first time i went through i had the turbo hooked up. and when they opened the hood i came out and asked him what he was doing. he was like ummm.... im looking for the egr valve. and closed the hood and told me i flunked. just goes to show... they know nothing about cars.

 

[io_303]

The first time i failed with the B16, he told me i had no PCV valve an pointed valve my breather after arguing for about 15 min, and me explaining what PCV was and where the crankecase was i reached under the manifold, and pulled it off, and told him he was an idiotshut my hood, got the printout and left

Swaps are fine in STL, but I still have to pass emissions for the original D15

i heard that you could swap engines, but the engine that you are swapping in has to come stock in that same model and year car.
