A fuel vapor pressure measuring device is provided, in a fuel supplying system, with a fuel tank for containing fuel, a fuel pump for supplying the fuel in the fuel tank to an injector, a fuel vapor generating section having a nozzle, a vaporizing chamber, and a venturi and vaporizing, in the vaporizing chamber, fuel by ejecting the fuel from the nozzle and causing the fuel to pass through the venturi, a first fuel path for interconnecting the fuel pump and the injector, a second fuel path having one end connected to the fuel pump and the other end connected to the fuel vapor generating section, a pressure sensor for detecting the pressure in the fuel vapor generating section, and an ECU for calculating the pressure of fuel vapor based on the result of detection by the pressure sensor. The fuel vapor generating section is mounted in the fuel tank.
