ditch the charcoal canister for a fuel line
I know a lot of guys have ditched the charcoal canister so that they could use that line for a fuel line. Are there any adverse effects by not having a canister? Doesnt the fuel tank vent to the char canister? What did you do with the vent? Just let the vapors go to atmosphere or what?

How exactly does the charcoal canister work? What happens to the vapors in the canister? Dont they leave the canister and go to the uim where the engine then sucks them up? Is that how it works?
If so could I just run a vac line form the tank to the uim for the vapors....well I guess not cause it seems like it could possibally suck up fuel into the engine or something.
How the hell does this system work exactly...anyone know? Did everyone have the same experience as Dubulup with the fuel smell being real strong when the tank is full???

One data point
The canister is basically a resevoir for fuel fumes. The purge system controls when the canister if evacuated via vacuum from the UIM. Can't remeber the exact workings in any greater granularity as it's been a while since it dealt with it.
The extra (EVC) fuel line idea I first heard from Cam a good 8 years ago when I was dicussing my fuel system upgrade. Needless to say I decided to go what has now become the more classic route of AN fittings and SS braided lines.
On my second car without an evac system, and I've never notice any particularly strong fuel scents. I left the two way valves in place on top of the tank. Perhaps the 'birds-dropping-out-of-the-sky" caustic emission coming out of my poulty roaster in the back have masked the scent of fuel so that a blood hound couldn't detect the smell. ;-)
