So I've replaced the gas cap, evap solenoid and vacuum lines with OEM ones, not cheap knock off brand.
this check engine light only happens when it is hot in the summer (does not happen in fall winter spring), so the fuel vapors are venting off and escaping I think? I would think there is a legitimate leak but I'm no expert.
Where else could this EVAP leak be coming from?

 

There's a million little vacuum hoses related to the EVAP system since there's so many solenoid valves; purge valve, tank vent valve, canister valve, etc.

The only way to pinpoint exactly where its leaking is by smoke testing the EVAP system. Will point you exactly to the leak.
