A marine craft includes a pollution control device for marine fuel tanks. The pollution control device includes a compartment for receiving fuel that leaves the fuel tank headed toward the vent via the vent line. The volume of the compartment desirably holds more fuel than would be contained in the volume of the length of the vent line that extends from the fuel tank to the vent. The compartment has an inlet that communicates with the fuel tank via the vent line. The compartment has an outlet that communicates with the vent via the vent line. The device includes a guide tube disposed within the compartment for preventing direct transmission of fuel to the vent. The device includes a float member disposed within the guide tube for detecting fuel in the vent line. The device includes an alarm circuit activated when the float member is located at a predetermined position within the guide tube. The device includes a lifting arm connected to the float member and enabling the float member to be lifted to a position where the operative alarm circuit should activate a signal.
