  • a collection tank having upper and lower ends;

    a divider mounted in a lower end of said collection tank that defines a relatively small sub-reservoir therein;

    a first inlet to said collection tank located in the bottom of said sub-reservoir, that admits a flow of fuel from said vent line;

    a second inlet to said collection tank located on a side of said divider opposite said first inlet, that admits an additional flow of fuel from said vent line;

    an outlet from said collection tank that allows displaced air to escape from said tank; and

    a liquid level sensor mounted in said sub-reservoir defined by said divider, that actuates an alarm circuit in response to said sub-reservoir filling with fuel entering via said first inlet in said sub-reservoir.
