A fuel smell near the filler, drips or wet stains around the neck, or rust and cracks on the neck or hose can mean it is failing. With the engine off and cool, look over the visible neck and hose first. A tank or vent line leak can look similar, so find the source before replacing it, and leave anything under the vehicle to a shop.
