I smell gasoline every time I fill up the gas tank and don't smell it when not quite full. I haven't check yet but I think that the fuel pump flange has deteriorated. My CO-worker has the same exact issue and he found out that it was the fuel pump flange. There was a safety recall about this issue back in 2013 and I was not sure if this issue was corrected before on my vehicle and think this needs to be recalled again. Please investigate. Thank you.
