Gasoline smell/may need fuel tank

[BigLew]

I think McGiillicuddy is probably right. If you get the smell when you are "burping" the tank on a full fill, you are probably pushing gas/fumes up the vent hose due to the filling pressure of the gas nozzel pushing gas into the tank.

Allow it to burp, and the SLOWLY top it off if you must. A half gollon or so may not make that much difference normally. Every pump has a slightly different shut off pressure and at least half of them will push gas up/above ahead of the resting level.
