A fuel safety valve arranged in a fuel supply line between a low-pressure pump and a high-pressure pump, is provided with a valve body which defines a cylindrical cavity having a longitudinal axis and being connected to a duct and a portion of a discharge duct in communication with the cylindrical cavity, a piston sliding with respect to the valve body in the cylindrical cavity along the longitudinal axis, and a spring housed in a variable-volume chamber defined by a portion of the cylindrical cavity between the piston and a closure element. The piston is provided with a through hole supplied with the fuel leading into the variable-volume chamber, and the valve body being provided with a fuel discharge hole connecting the variable-volume chamber to the discharge duct.
