Abstract
Methods and systems are provided for a vapor canister couple to a fuel tank of a vehicle. A series of fluidically coupled, variable capacity bleed elements, externally coupled to a sidewall of the vapor canister, capture the bleed emissions resulting from desorption of fuel vapors from an adsorbent material inside the vapor canister. The series of bleed elements may be fluidically coupled through flow paths passing through the vapor canister wall, connecting through a first flow path to a chamber inside the vapor canister and connecting through a second flow path to a vent port of the vapor canister.
