I have a 2011 dodge charger se/rallye 3.6 rwd.142,000 miles. I have an evap code show up, possible fuel filler neck. I'll replace when part arrives. But I've had the evap issue for about a year an a half. Replaced leak detection pump twice. I would smell gas inside the cab. I pulled the seat, inspected primary fuel pump and sending unit. Sending unit displayed signs of gas leak. Discolored, small darker cracks on top in ridges. I replaced with a Delphi sending unit. Ran fine for about 170 miles. Then code showed back up, being that I pulled the battery cable to change sending unit, one morning when I tried to start her. Not to mention, the start was struggling for gas, I assume. I would wait 15 mins, prime lines by powering units with key, then start. Much better, but still struggles. Could that be the evap leak, or should I replace the primary pump as well. Fuel regulator? What about a purge valve solenoid? I should mention that I'm not noticing fuel issue while driving, however I'm not galavanting or hot roddin it.
