ABSTRACT:
A fuel tank, which is equipped with two fuel outlet tubes that are merged to one fuel injection pipe to engine, is provided. First fuel outlet tube is located at a corner of the bottom of the fuel tank. Second fuel outlet tube is located on a wall just 2.5 centimeter above the first fuel outlet tube. A fuel level gauge, on instrument panel in front of a driver's seat, turns on ‘red’ signal when a floating valve in the fuel tank reaches to a level 2.5 centimeter above the second fuel outlet tube. When the floating valve reaches a level of the second fuel outlet tube, needle of the level gauge indicates the bottom of the level gauge. Though the gauge indicates that the fuel tank is empty, gasoline in the fuel tank is fed to the engine. Purpose of the current invention is to alert the driver of the vehicle that fuel must be charged immediately.
