Answer
Hi Bob -

Have you noticed a drop in gas mileage? If not, you probably do not have a leak, especially if you don't see any fuel on the ground when you are idling.

I would check the gas cap. Sometimes it is not venting properly and the fumes are backtracking.

Also check the fuel tank area connections. the rubber vent lines could be cracked and venting fumes out that way.

Hope this helpa
