You should have it looked at, the emissions are supposed to store fuel vapors, there may be a small leak. Its a fairly high pressure system, and it should not be hard to locate. See if you can see any fuel dripping under the car, the fuel tank and charcoal cannister are the only places raw fuel are stored. A hose may be leaking. Its not safe. The charcoal cannister may be soaked with too much fuel. Happens on some older cars.
Be careful with fuel smells. Ok
