Need help with EVAP leak please

[MrLegit827]

Hi everyone,

I have a gross evap leak. I haven't replaced the purge valve yet because I want to see if there are any cracked lines/hoses that could be causing it instead.

I made myself a DIY evap smoke tester and it works perfectly. I haven't tested it in my car yet. My question is, where do I hook it up to test my cobalt's evap lines? The two purge valve lines? Anywhere else possible?

Thanks
