Abstract
A system for reducing escape to the atmosphere of hydrocarbon fuel vapors from a fuel tank for a combustion engine powered device including at least one functional member that directly communicates with the fuel tank and is constructed to receive and retain hydrocarbon vapors therein. The functional member may further include a bed of activated carbon-based material for adsorbing and purging of the hydrocarbon vapors. The functional member is otherwise useful to the device beyond the vapor handling function and may be incorporated into a handlebar assembly, frame component, housing, cover, and the like thereby reducing component parts and reducing cost and complexity of the device.
