The present invention provides a residual amount check method of a fuel tank, which comprises the following steps of: storing density of fuel, a type of fuel, the amount of fuel in a fuel tank, and output pressure applied to the fuel tank in a control unit; storing a type of fuel, an inclination, and output pressure in the control unit; storing database in a microcontroller; and checking the amount and density of fuel in the fuel tank. The density and a residual amount of fuel can be figured out for a user to objectively determine honest goods and the required amount of fuel. |
