An integrated premixture chamber is disclosed, for mixing gaseous fuel and air for delivery to a combustion chamber of an internal combustion engine. The integrated premixture chamber includes a mass air flow sensor, a throttle valve and position sensor, a fuel shut-off valve, a gas flow sensor and a fuel metering valve having discharge outlets downstream of the mass air flow sensor to provide more accurate metering. The integrated premixture chamber is controlled by an electronic unit separate from the engine\s control unit.
