Abstract
A fuel vapor recovery system for an automotive vehicle includes a fuel tank, a first vapor recovery canister, a second vapor recovery canister, and a bypass flow metering element. The first canister has an inlet communicating directly with the fuel tank and an outlet. The second canister has an inlet communicating directly with the outlet of the first canister. The bypass flow metering element is disposed between the inlet and outlet of the first canister and directs a predetermined portion of the vapor from the tank directly to the inlet of the second canister, thereby reducing the vapor flow restriction through the system.
