Usually you'll smell a fuel leak long before you see the puddle on the ground. Check all your lines and see if any are wet

Where do i do that? I do body work and know nothing about engines and it doesn't leak a lot because i never see any in the garage

It's not me I been eating Certs all day so mine don't stink! LOL:D JK

Try starting at the gas tank underneath and follow your lines to the front and then under the hood. Try while not running first, then start it up and check again. Just a start.

Could also be the evap canister. start with the fuel lines though. DON'T wait on finding the problem though, fuel leaks are serious.

the smell comes from the engine where the air filter is

Look for a fuel leak on the intake and check all fuel line connections around the engine.. The heat would make a small leak evaporate before it drips if it's at a connection on top of the intake..
