An air filter element is disposed in the internal volume. The upper portion of the filter housing includes a canister port adapted for fluid connection with an evaporative emissions canister. The lower portion of the filter housing includes a first port adapted for fluid connection with an atmospheric vent, and a second port adapted for fluid connection with a source of low pressure air.
