An engine fuel heater for an internal combustion engine where the fuel entering the carburetor is kept at a pre-determined temperature regardless of ambient air conditions. The device includes a heat exchanger for transferring heat from the hot water of the engine to the gasoline, a read station where the temperature of the gasoline is read, a bi-metal thermostat responsive to the read station which controls whether a vacuum is maintained inside a vacuum chamber, the presence of a vacuum within the vacuum chamber controlling whether water flows into the heat exchanger.
