Abstract

A fuel tank system constructed in accordance to one example of the present disclosure includes a fuel tank, a first vent tube, an evaporative emissions control system and a cam driven tank venting control assembly. The first vent tube is disposed in the fuel tank. The evaporative emissions control system is configured to recapture and recycle emitted fuel vapor. The evaporative emissions control system has a controller. The cam driven tank venting control assembly has a rotary actuator that rotates a cam assembly based on operating conditions. The cam assembly has at least a first cam having a first cam profile configured to selectively open and close the first vent tube based on operating conditions.
