My 2005 Sedona had developed a fuel smell today,

Verry strong when running, Its going to be sent to the dealer because its still under warranty. Our high temp today was 111 degrees I had both a/c on full and it ran fine it has 13683 miles. Would the smell be from the evaporation due to the high temperatures today? I dont know. Maybe an emisions part had failed? I'll find out from the dealer when they put it on the hoist. If anyone has had a similar problem please inform me.

Thanks,
