Abstract
An evaporative emissions control fuel cap system comprises a closure adapted to mate with a fuel tank. The closure includes a passageway formed therein to conduct vapors from the fuel tank to the atmosphere. The closure includes a filter configured to capture hydrocarbons positioned in the passageway so that fuel vapor flowing from the fuel tank is scrubbed of hydrocarbons before being discharged to the atmosphere.
