Venting systems and methods are provided for a fuel system of an engine. In at least one example, the fuel system includes a fuel tank connected to a vapor recovery canister via a main conduit. The venting system includes an electrically actuated vent control valve, a plurality of sensors, and a control unit coupled to the sensors and to the electrically actuated vent control valve. The vent control valve is configured for being installed in the main conduit to thereby enable selectively opening or closing fluid communication between the fuel tank and the vapor recovery canister. The plurality of sensors are configured for providing data indicative of conditions relating to the tank. The control unit is configured for operating the electrically actuated vent control valve to open or close the fluid communication according to first predetermined criteria, wherein the first predetermined criteria include minimizing risk of liquid carry over (LCO) from the fuel tank to the vapor recovery canister. A corresponding method is also provided.
