Hello. Im new to the site. Hopefully someone can shed some light on my problem. When I start my truck I get a bad fuel odor. It seems like its coming from under the hood, and it comes into the cab. Ive checked under the hood, and there are no leaks anywhere that I can see. The funny thing is, it goes away after about a minute or so. Could this be something with my emission crap under the hood? Thanks for any input guys.

 

Check hoses to evaporator can under battery.
