Buzzing sound from fuel door?
 

So I just hit 42k miles, 7AT, regularly do ALL maintenance, some way sooner than needed. Noticed about 2 weeks ago this constant buzzing noise whenever my car is running. The noise seems to be constant, no matter how fast or slow I'm driving from what I can tell. I can hear it from the interior but not nearly as much as outside. It sounds like it's coming more so from passenger side rear by the fuel door. Could this be a fuel pump issue? Video below for better clarity (might need to turn volume up to hear it since my exhaust is aftermarket).
