Abstract
An overflow device for a vehicular carburetor. The carburetor includes a float chamber in which a maximum level is to be maintained. A drainage tube drains fuel at higher levels to a reservoir at an elevation lower than the carburetor. A vent tube vents the reservoir at an elevation higher than the carburetor. The reservoir can be heated by engine heat to evaporate excess fuel.
