Abstract:
1. A system for preventing a fuel spill from a connecting line extending between a first and second reducer fitting on a first and second fuel tank, respectively, wherein the first fuel tank is in pressure communication with the second fuel tank such that fuel flows from one of the first and second fuel tanks to the other when there is a pressure difference between the pressure acting on fuel in the first fuel tank and in the second fuel tank, the system comprising: (a) a first safety valve immersed in the fuel in the first fuel tank, wherein the first safety valve has an outlet coupler connected to the first reducer fitting, and wherein the first safety valve has an inlet coupler through which fuel enters the first safety valve; (b) a second safety valve immersed in fuel in the second fuel tank, wherein the second safety valve has an outlet coupler connected to the second reducer fitting, and wherein the second safety valve has an inlet coupler through which fuel enters the second safety valve; and (c) wherein each of the first and second safety valves comprises:
