Ls1 to LS3 conversion - EVAP questions

What EVAP system do I need to order to connect an LS3 style intake and fuel system to the current lines in my LS1 (from firewall back)? I've seen this diagram from the G8 which looks like it might fit my application, but I'm unsure if the hose (part # 92203255) will hook up to the current LS1 EVAP lines. Any advice? I've been researching for days on just this issue.

Thanks for the help,

-Chris

Are you talking about the little purge soleniod and line that goes back to the tank? If so mine connected just like the stock manifold. My fuel lines are custom. I think the connectors are the same.

Did you use the LS3 evap system or the LS1 evap on the new (LS3 style) intake? If I'm understanding you, the stock LS3 system would connect to the LS1 connectors near the firewall?

Thanks!
