Fuel feeder for automotive engine

摘要

A fuel feeder for an automotive engine, which comprises a fuel tank with a sub-tank provided therein for feeding fuel from the sub-tank to an engine. Excess fuel returned from the engine is led to an overflow chamber disposed in the sub-tank and thence overflows into the sub-tank. Normally, the overflow chamber is thus full of returned fuel. When the fuel in the sub-tank is brought to one side due to a sudden acceleration or deceleration or a turning of the vehicle, the fuel in the overflow chamber is also brought to the same side and overflows from the overflow chamber, thus increasing fuel in the sub-tank.
