ABSTRACT:
An improved fuel supply system for an internal combustion engine, which sem is of the type including a fuel reservoir connected to a pump to supply the carburetor with more fuel than required by the engine, and a recycling system for recycling the excess fuel to a predetermined point in the fuel supply system upstream of the carburetor. The recycling system includes a recovery chamber for collecting excess fuel, a duct for feeding the excess fuel from the recovery chamber to an intermediate chamber, and a duct feeding fuel from the intermediate chamber back into the supply system at the predetermined point. The last-mentioned duct is controlled by a float valve responsive to the level of fuel in the intermediate chamber.
