Abstract
A vapor fuel recovery system for fuel tanks is provided. The vapor recovery system comprises: a canister that captures vapor fuel expelled from the fuel tank; a vent valve that controls ventilation of vapor fuel from the fuel tank to the canister; and a vent bypass disposed between the canister and the vent valve that controls the flow of vapor fuel from the fuel tank to the on-board recovery canister when a fuel level in the fuel tank is full. The bypass includes a bypass valve and at least one orifice.
