A fuel gauge for a vehicle is provided to vary actual length of a cable and compensate fuel amount depending on the shape of a fuel tank having different sections based on the height, thereby measuring the amount of fuel more accurately. A fuel gauge for a vehicle includes a fuel tank(10), a cable, and a circuit part. The cable is inserted in the fuel tank. The circuit part is connected to an upper end of the cable to measure high frequency supply and reflection waves. The cable is installed in a plastic or glass pipe having an open lower end, and fuel is filled between the cable to prevent rapid height variation of the fuel due to movement of the vehicle. A chip load resistor is attached to a lower end of the cable. The cable and the load resistor are waterproofed by urethane or vinyl resin. |
