Abstract
A fuel cap configured to be coupled with the opening of a fuel tank defining an interior for containing a volume of fuel. An inlet opening is configured to establish fluid communication with the fuel tank interior. An exit is in communication with a surrounding atmosphere, exterior to the fuel cap. A flow path is defined from the inlet opening to the exit. Adsorption media substantially fills the flow path and is configured to reduce the emission of VOC vapors through the exit to the surrounding atmosphere. The flow path extends spirally about an axis of the fuel cap from the inlet opening to the exit.
