One of the studs broke off from the salvage I was pulling out. It's exactly like a fishtank filter. Exactly the same thing except instead of fish gunk it's gas gunk.

Cool, how did you cut it open.

just a hacksaw to the bottom. on the other side there is a second grid and filter with a tube for moisture. it's a pretty simple thing.

the white cotton filters were as new as bedsheet from the store, untouched from time of assembly! this one is from a '96, and it wasn't clogged at all. it is pressurized so there are no openings to it.

they don't even show this on the hyundai diagrams. poor thing i feel like Hannibal Lecter...

Can you analyze it's operation from the dis assembly?

Is there a specific flow pattern? What are the various components for? Those springs push against the cotton?

I know this threat is old. But do you think it would be possible to replace the charcoal without cutting it open. Also what hyundai use the same canister as a rd2. I am having trouble finding a rd2 at my local yard.

probably not, they are sealed so its pretty much impossible to replace the charcoal. Why would you want to?

Well as you all know I being having trouble with my gas tank not filling up because the canister must be clogged up. I already replaced the lines and the purge control valve my car has 105000 so the only thing I can think of is that the charcoal has become solid and gunk up. Or I need to replace the actual evap tank but I do not wan tto spend $90 on a new one

There is also a solid line that goes from the fil neck of the gas tank down to the charcoal canister, have you checked that one?

The filter (the white part in the 1st photo) might also be caked with mud. My parts car's sure was.

I suppose if it pulls in enough dusty air that when it catched the fuel overflow it will create mud...
