A fuel/vapor separator apparatus for de-vaporizing fuel entrained with vapor has a hollow canister defining a separation chamber. The canister has an input port for receiving the fuel entrained with vapor, an output port in communication with the engine for removal of the de-vapored fuel from the chamber, and a vapor port for removal of the released vapor from the chamber. A screen element is located in the separation chamber of the canister between the input port and the output port for agitating the fuel to release the vapor from the fuel. The apparatus has a valving arrangement for connecting the vapor port to the reservoir. The valving arrangement has at least three ports. The vapor port of the canister is in communication with the first port of the valving arrangement. The reservoir is in communication with the second port of the valving arrangement, and ambient air is in communication with the third port. The valving arrangement has a conduit with a control pin for selecting the venting of the separation chamber through the vapor port to either the fuel tank or the ambient air.
