PROBLEM TO BE SOLVED: To provide a fuel display system for preventing an indicated value from changing and a user from mistaking a pressure reduction in a compressed natural gas (CNG) cylinder, caused by temperature differences between day and night after a high pressure CNG is filled at a filing location, for a leakage of the CNG and a fuel gauge used for the same. SOLUTION: The fuel display system of an automobile using the compressed natural gas as a fuel is provided with a pressure measuring means (12) for measuring pressure in a supply system (A) of the fuel compressed natural gas, a temperature measuring means (16) for measuring temperature in a pressure container (the cylinder 1) for storing the compressed natural gas, a control means (14) for computing the mass of the stored compressed natural gas on the basis of the results of the measurements by the pressure measuring means (12) and the temperature measuring means (16), and a display means (the fuel gauge 18) for displaying the mass of the compressed natural gas computed by the control means (14).
