<p>A fuel-delivery control system (10) for a fuel tank (12) includes a housing module (62) formed to include a fuel-delivery channel (64) and a check valve assembly (66) positioned to lie in fuel-delivery channel (64). Check valve assembly (66) includes a support base (88) appended to housing module (62), a valve member (90) slidably coupled to support base (88) for movement between a channel-closing position engaging housing module (62) and a channel-opening position disengaging housing module (62). Support base (88) and valve member (90) are formed to include a closed interior region (130) therebetween. A spring (92) lies in closed interior region (130) and yieldably urges valve member (90) toward its channel-closing position. <IMAGE></p> |
