Method of filling a fuel tank
A method of initially filling a new and previously unused fuel tank with a fuel including Volatile Organic Compounds includes providing a dispensing unit with an elongated flexible dispensing tube, inserting the dispensing tube through a fuel inlet of the fuel tank until the dispensing tube is disposed adjacent a bottom surface of the fuel tank, and introducing the fuel onto the bottom surface of the fuel tank in a smooth flow without spraying the fuel. Introduction of the fuel onto the bottom surface of the fuel tank in a smooth flow disposes any fuel vapors formed therein adjacent the bottom surface of the fuel tank to limit displacement of the fuel vapor into the atmosphere outside the fuel tank as the air in the fuel tank is exhausted in response to filling the fuel tank.
1. A method of filling a fuel tank having a vapor outlet and a fuel inlet disposed adjacent a top surface of the fuel tank and a neck portion extending from the fuel inlet along a curvilinear path to a filling end, with a fuel including volatile organic compounds, the method comprising:
providing a dispensing unit having an elongated flexible dispensing tube extending from the dispensing unit to a distal end and configured to introduce the fuel into the fuel tank;
inserting the elongated flexible dispensing tube through the filling end of the neck portion, along the curvilinear path of the neck portion, and through the fuel inlet until the distal end of the flexible dispensing tube is disposed adjacent a bottom surface of the fuel tank; and
introducing the fuel into the fuel tank adjacent a bottom surface of the fuel tank so that any fuel vapors formed during introduction of the fuel into the fuel tank are disposed adjacent the bottom surface of the fuel tank to limit exhaust of the fuel vapors through the vapor outlet during introduction of the fuel into the fuel tank.
2. A method as set forth in claim 1 wherein introducing the fuel into the fuel tank is further defined as introducing the fuel onto the bottom surface of the fuel tank in a smooth flow without spraying the fuel to minimize turbulence in the flow of fuel.
3. A method as set forth in claim 1 wherein inserting the elongated flexible dispensing tube through the fuel inlet until the distal end of the dispensing tube is disposed adjacent a bottom surface of the fuel tank is further defined as inserting the elongated flexible dispensing tube through the fuel inlet until the distal end contacts the bottom surface of the fuel tank.
4. A method as set forth in claim 1 further comprising installing the fuel tank in a vehicle prior to inserting the flexible dispensing tube through the neck portion of the fuel inlet.
5. A method as set forth in claim 4 further comprising providing the fuel tank in an unused and empty condition.
6. A method as set forth in claim 5 wherein the volatile organic compounds of the fuel include hydrocarbons.
7. A method as set forth in claim 6 wherein the fuel includes a Reid Vapor Pressure of at least 7 psi.
8. A method as set forth in claim 1 wherein the fuel tank contains a volume of air prior to introducing the fuel into the fuel tank and wherein the method further comprises exhausting at least a portion of the volume of air from within the fuel tank through the vapor outlet into the atmosphere in response to introducing the fuel into the fuel tank.
9. A method of filling a fuel tank having a fuel inlet disposed near a top surface of the fuel tank and a neck portion extending from the fuel inlet along a curvilinear path to a filling end, with a fuel including hydrocarbons, the method comprising:
providing a dispensing unit including an elongated flexible dispensing tube extending from the dispensing unit to a distal end;
inserting the elongated flexible dispensing tube through the filling end of the neck portion, along the curvilinear path of the neck portion, and through the fuel inlet until the distal end of the dispensing tube is disposed adjacent a bottom surface of the fuel tank;
introducing the fuel into the fuel tank adjacent the bottom surface of the fuel tank so that any fuel vapors formed during introduction of the fuel into the fuel tank are disposed adjacent the bottom surface of the fuel tank to limit exhaust of the fuel vapors through the vapor outlet during introduction of the fuel into the fuel tank; and
withdrawing the flexible dispensing tube along the curvilinear path of the neck portion to remove the flexible dispensing tube from the fuel tank and the neck portion after the fuel is introduced into the fuel tank.
10. A method as set forth in claim 9 wherein introducing the fuel into the fuel tank is further defined as introducing the fuel onto the bottom surface of the fuel tank in a smooth flow without splashing the fuel to minimize turbulence in the flow of fuel.
11. A method as set forth in claim 10 wherein the fuel tank contains a volume of air prior to introducing the fuel into the fuel tank and wherein the method further comprises exhausting at least a portion of the volume of air from within the fuel tank through a vapor outlet into the atmosphere in response to introducing the fuel into the fuel tank.
12. A method as set forth in claim 11 further comprising installing the fuel tank in a vehicle prior to inserting the flexible dispensing tube through the neck portion of the fuel inlet.
13. A method as set forth in claim 12 further comprising providing the fuel tank in an unused and empty condition.
14. A method as set forth in claim 13 wherein the fuel includes a Reid Vapor Pressure of at least 7 psi.
15. A system for filling a fuel tank of a vehicle with a fuel including volatile organic compounds, the system comprising:
a conveyor apparatus configured for conveying a plurality of individual vehicles along an assembly line; and
a dispensing unit disposed adjacent said conveyor apparatus and configured for dispensing the fuel into the fuel tank;
said dispensing unit including an elongated flexible dispensing tube extending from said dispensing unit to a distal end and configured for insertion through a neck portion of a fuel inlet of the fuel tank along a curvilinear path to a bottom surface of the fuel tank to dispense the fuel onto the bottom surface of the fuel tank in a smooth flow without splashing the fuel to minimize turbulence in the flow of fuel such that any fuel vapors formed during introduction of the fuel into the fuel tank are disposed adjacent the bottom surface of the fuel tank to limit exhaust of the fuel vapors through the vapor outlet during introduction of the fuel into the fuel tank.
16. A system as set forth in claim 15 wherein said dispensing tube includes a length sufficient to extend from the dispensing unit to the bottom surface of the fuel tank.
17. A system as set forth in claim 16 wherein said length is at least 36 inches.
18. A system as set forth in claim 16 wherein said dispensing tube includes a flexible material permitting non-uniform curvilinear insertion of said dispensing tube through the neck portion of the fuel inlet of the fuel tank.
19. A system as set forth in claim 16 wherein said distal end of said dispensing tube contacts said bottom surface of said fuel tank.
