Abstract
A fuel-delivery control system is provided for use in a fuel tank. The fuel-delivery system includes a housing module formed to include a fuel-delivery channel and a check valve assembly positioned to lie in the fuel-delivery channel. The check valve assembly includes a support base formed to include a guide passageway, a mounting fixture inserted into the fuel-delivery channel and arranged to interconnect the housing module and the support base, a valve member, and a spring. The valve includes a guide stem extending into the guide passageway for movement therein and a closure member appended to the guide stem for movement with the guide stem between a channel-closing position engaging the housing module and a channel-opening position disengaging the housing module. The guide stem moves in the guide passageway as the closure member moves between the channel-opening position and channel-closing position. The spring yieldably urges the valve member to its channel-closing position.
