A fuel supply device for an internal combustion engine comprises a constant level chamber (typically a float chamber) formed in a casing which may be the body of the carburetor of the device. A heat exchanger is formed in the casing or in contact with the casing. A cooling liquid is circulated in a closed-loop circuit including the heat exchanger and a liquid reservoir having a large volume as compared with that of the balance of the circuit.
