How can I vent my tank without getting a gas smell?

[Mecom Racer]

I have a 21 gal. fuel cell that I have vented through a metal tube at the top with what I thought would be a high enough bend (8"-10" above the tank) to keep fuel from spilling out...

...but when cornering fast with anything more than a half tank, I get fuel dripping out of my vent tube that exits into my wheelwell. Plus it makes my garage smell like gasoling from venting into the atmosphere. Any way I can fix this or is this pretty normal?

Anyone have pics of their fuel tank venting solutions?
