I'm at wits end looking for this EVAP leak ! I've took it to a shop and got it smoked and they said it was the charcoal canister.I replaced the charcoal canister ( oem with new leak detection pump) replaced the gas cap with an oem mopar cap. I replaced the purge valve. I went so far as to buy a smoke machine and smoked it myself, and I found no leaks. I'm out of ideas and have nowhere else to look... All of the write ups I've seen the remedy was a fuel cap or leak detection pump. Has anyone had to replace anything else other than these pieces ?
