Patent ID: 8430117

Claim:
A refueling system for a vehicle, said refueling system comprising: a fuel tank, said fuel tank having a side wall, said fuel tank having an internally threaded port through said side wall, said port having an inside diameter of three-quarters of an inch or less; a fluid flow control valve configured for connection with a fuel source, said fluid flow control valve connecting to a bleed line; said bleed line interconnecting said fluid flow control valve and a float control module; said float control module connecting to said bleed line, said float control module having an open position where bleed fluid may flow from said bleed line through said float control module and into said fuel tank, said float control module having a closed position where bleed fluid is prevented from flowing through said float control module, said open and closed positions controlled by the raising and lowering of a float portion, said float control module comprising: an externally threaded portion having threading configured for threading into the port's internal threads, said externally threaded portion comprising a housing configured for rotatably receiving a drum of a central assembly therein, said central assembly comprising said drum rotatably received in said housing, an inlet port, an upper inlet bore defined through said central assembly, said upper inlet bore extending from said inlet port to an outlet port, and said outlet port, said outlet port fluidly connecting to a valve assembly, said valve assembly having a diameter smaller than said port inside diameter, said valve assembly for interrupting the flow of said bleed fluid through said float control module, and a float portion having a diameter smaller than said port inside diameter, thereby enabling said valve assembly and said float portion to be inserted through said port and into said fuel tank; wherein in said open position the flow of the bleed fluid through the bleed line is prevented, triggering the control valve to close, thereby preventing a flow of fuel from said fuel source from flowing through said fluid flow control valve into said fuel tank; and wherein in said closed position the flow of the bleed fluid through the bleed line is permitted, thereby triggering the control valve to open and permitting a flow of fuel from said fuel source through said fluid flow control valve and into said fuel tank.
