The fuel sensor and value was replaced though. Maybe that wasn't installed properly?

How can they flag something that they didn't see?
Most likely is the installation. EVAP is a close system, if there is a leak, that's when it gives you the CEL.
So, unless you mess around with the fuel system other than the gas cap, they should fix it.
