Thanks, 71jimmy. I read once that it was one of the few smog devices that actually improved efficiency and with the EFI setup I kinda got forced into researching it...

As far as the gas smell... hooked up this way it's a closed system. The cap is not vented, so even with the engine turned off you're not apt to get the gas smell around the cap like you would with a vented system. I have no gas smell at all now. Before I hooked up the canister, it stunk up the garage enough that the wife was complaining. (all that work and it smells like gas!!)
