A fuel feeding apparatus for internal combustion engines, of the type having a heat-type air flow meter disposed in a bypass air passage detouring an air-intake passage, an air metering valve adapted to be actuated by a proportional type electromagnetic device to control the flow rate of air in the bypass air passage substantially at a constant level in response to the output signal from the heat-type air flow meter, and a fuel metering valve adapted to be actuated by the proportional type electromagnetic device simultaneously with the control of air flow rate by the air metering valve. A pulsation suppressing means is disposed in the bypass air passage to suppress the pulsation of air pressure in the latter thereby to decrease the measurement error in the heat-type air flow meter.
