fuel smell

I let the LC get pretty low recently on a drive and now after a refill of fuel, I get a slow start and smell fuel from the outside. I admit I’m at a loss, I can’t see fuel puddling or leaking. Where can I start troubleshooting here? TIA!!

I finally rid myself of all the common CEL codes. This required replacing nearly the entire EGR system, fuel injector cleaning, manifold cleaning, and new O2 sensors to name just a few of the efforts I undertook. I’m excited the codes are gone but there is a raw gas smell. I think it’s coming...
