Abstract
A carbon canister filter box having an integrated cap. The integrated cap incorporates one or more components, such as vent solenoids, pressure sensors, an internal honeycomb feature for assisting in trapping hydrocarbons from the fuel vapor, and purge ports. The integrated cap sealingly attaches to a carbon canister vapor recovery system and can be manufactured to be implemented on existing canister units. The cap connects to the automotive emission storage canister in relation to the fuel tank of the vehicle, used to recapture fuel vapor before it is released into the atmosphere. A sealing means is positioned between the cap and the canister, preventing the leakage of fuel vapor into the outside atmosphere.
