Abstract
A fuel system for an internal combustion engine employs a conduit connecting a fuel tank to a canister. A two-way valve in the conduit opens to permit flow when vapor pressure in the fuel tank exceeds a predetermined limit or falls below a predetermined limit. A bypass line is connected to the conduit, bypassing the two-way valve and containing an electrically-operated valve device which opens in response to closing of two series-connected switches, the first switch automatically closing when the engine is running, and the second switch closing when the engine coolant reaches a high temperature.
