Liquid reservoir systems are disclosed. In one embodiment, a liquid reservoir system may capture and retain a fuel reservoir to provide an uninterrupted fuel supply to a fuel pump or pickup line during low fuel conditions such as those that may be experienced during vehicle acceleration, braking or side to side maneuvers. It may also capture and retain a fuel reservoir to provide an uninterrupted fuel supply to a fuel pump or other pickup line during periods of high agitation such as may be experienced during vehicle jumping, cross country/closed course racing and other aggressive driving maneuvers.
