Abstract: A supporting structure for a fuel filter assembly provides a latch which is manually movable without the necessity of tooling into either a locking position or an unlocking position. By manually moving the latch, a collar of the fuel filter assembly can be freed to rotate about a supporting cover so that the reservoir can be removed. The assembly can also be manually removed from a support bracket without the use of tooling. The fuel filter assembly provides a resilient mounting system that isolates the fuel filter and its associated components from the vibrations that are inherent in an internal combustion engine.

Abstract: A fuel supply system for a marine engine provides an additional fuel chamber, associated with a fuel vapor separator, that receives fuel vapor from a vent of the fuel vapor separator. In order to prevent the flow of liquid fuel into and out of the additional fuel chamber, a valve is provided which is able to block the vent of the additional chamber. In addition, a sensor is provided to provide a signal that represents a condition in which liquid fuel within the additional fuel chamber exceeds a predetermined level.
