Fuel smell inside car?

2012 TOYOTA Camry SE 4 cyl.
My fuel line came out and my
husband bought another clip to
secure it, also its a brand new fuel
pump. We went from a full tank to
a qtr tank on our way home, then
he found what was wrong and
fixed it. But now we cant get the
fuel smell out of the car. The gas
did flow into the backseat area
when it happened. But we have
had the windows down, sprayed
with febreeze for a week now and
its still very strong. But no smell
outside of the car. HELP
