ABSTRACT:
A fuel supply system for an injection-type internal combustion engine using a gasoline or alcohol blended gasoline as a fuel. In addition to a conventional fuel supply system there is provided a fuel temperature detector which detects and signals the fuel temperature increases and exceeds a predetermined value and a fuel pressure regulating means responsive to the fuel temperature detector for raising the fuel pressure within the fuel supply line applied to each fuel injector above a constant value regulated according to the pressure difference between the fuel pressure within the fuel supply line and the intake manifold vacuum pressure so as to prevent the fuel supply line from being clogged due to the occurrence of vapor lock at the time when the engine is started at a high fuel temperature or when the engine runs at a low speed under a high fuel temperature.
