LS1 Gas Tank & Passing Smog

As some of you may know, the ls1 tank has an internal charcoal canister and an evap system that is essentially uncharted waters as far as making it work with the thirdgens. How does this work when attempting to pass smog? Any advice on what I need to do to get an ls1 gas tank set up smog legal would be much appreciated. Thanks for reading!

internal? it sits on top of the tank and works the same way as the stock thirdgen. The only problem your going to have is the visual.

For a Ls3 swap per say is not legal. You use your thirdgen tank in regards to that swap. Don't know if it's legal either way.

Re: LS1 Gas Tank & Passing Smog

the actual tank is legal on any motor. The ls3 charcoal canister and is the same as well so a ls1 tank would be no problem. if your simply looking to run the ls tank hook it just like factory and you will be fine.

I mean, I have the tank in the car, I just have to run the vacuum tube from the plenum to the tank's charcoal canister?
