Abstract
For use in combination with a system for separating water from pressurized fuel in a filter-separator tank, there is provided a float valve and weight device that prevents fuel from leaving the tank if the interface between fuel and water is at an undesirably high elevation. The float of the float valve is associated with a weight, the relationships being such that the float floats at the interface. To test the float for waterlogging, and to test the entire system, the association between float and weight is discontinued. The float then floats up unless waterlogging has occured.
