Electrically controlled fuel system module

A fuel tank system comprising:

• a fuel tank;
• a first vent line disposed in the fuel tank;
• an evaporative emissions control system configured to recapture and recycle emitted fuel vapor, the evaporative emissions control system having a controller;
• and
• a cam driven tank venting control assembly having:
• a rotary actuator that rotates a cam assembly based on operating conditions, the cam assembly having at least a first cam having a first cam profile;
• and
• a first valve that opens and closes a first port based on a position of the first cam, the first valve selectively communicating vapor to the first vent line based on operating conditions.

A fuel tank system comprising:

• a first vent line disposed in the fuel tank;
• a second vent line disposed in the fuel tank;
• an evaporative emissions control system configured to recapture and recycle emitted fuel vapor, the evaporative emissions control system having a controller;
• and
• a cam driven tank venting control assembly having:
• a rotary actuator that rotates a cam assembly, the cam assembly having a first cam having a first cam profile and a second cam having a second cam profile;
• a first valve that opens and closes a first port based on a position of the first cam, the first valve selectively communicating vapor to the first vent line based on operating conditions, wherein the first vent line is fluidly coupled between the first port and a first vent opening arranged in a vapor space within the fuel tank;
• a second valve that opens and closes a second port based on a position of the second cam, the second valve selectively communicating vapor to the second vent line based on operating conditions, wherein the second vent line is fluidly coupled between the second port and a purge canister;
• a housing that at least partially houses the rotary actuator;
• and
• wherein the rotary actuator includes a motor disposed on the housing and configured to rotate the cam assembly.
