Abstract
An evaporative venting system for use in an internal combustion engine and a method for venting fuel vapors are disclosed. The evaporative venting system includes a containment chamber at least in indirect communication with a fuel tank and a passageway defined within the containment chamber and having an inlet opening and an outlet opening. The inlet opening is at least indirectly in communication with the fuel tank and the outlet opening is at least indirectly in communication with an evaporative chamber such that the passageway provides a vent path between the fuel tank and the evaporative chamber such that the vent path allows for both the venting of fuel vapors from the fuel tank and the intake of air into the fuel tank during all angles of positioning of the fuel tank.
