A fuel supply device is proposed which serves to supply fuel to a mixture-compressing, externally ignited internal combustion engine with a good distribution of the fuel-air mixture. The fuel supply device includes a fuel metering device activated by an air metering device arranged in the air intake manifold of the internal combustion engine with the fuel metering device being connected to an air line in which the metered fuel is mixed with air before the injection into the air intake manifold. Between the air line and the fuel line, upstream from the fuel metering position, a filter having a fine-meshed weave is arranged by means of which the fuel is prevented from flowing out over the air line in an undesirable manner.
