Abstract

An assembly (10) is provided that integrates a jet pump (44 144) with a liquid trap to drain liquid fuel from vapor flow such as vapor vented from a fuel tank (22). The assembly includes a housing (12) that has a liquid trap (20) configured to trap liquid carried in vapor flowing through the housing. A jet pump (44 144) has a venturi nozzle (48 148) and is in selective fluid communication with the liquid trap so that liquid flow through the venturi nozzle induces draining of the liquid trap.
