Provided herein are couplings useful in the transfer of liquid fuels from a remote storage reservoir to an on-board fuel tank of a motorized vehicle. There is provided a first coupling which is configured to be in fluid communication with the interior of a vehicle's fuel tank, and a second coupling which is intended to be in fluid communication with the contents of a remote fuel storage reservoir. The disclosure also includes a process for charging a fuel reservoir on board of a motorized vehicle from a remote reservoir, wherein the vapor in the fuel reservoir is displaced by an equal volume of fuel delivered from said remote reservoir, and wherein the vapor in said fuel reservoir is simultaneously caused to be transferred to said remote reservoir, thus permitting no escape of the vapor from said fuel reservoir to the surrounding atmosphere. Through use of the present disclosure, spills of fuel are essentially eliminated, and the escape of vapors from the vehicle's fuel tank are prevented, thus preventing atmospheric hydrocarbon pollution.

What is claimed is: 1. A process for charging a fuel reservoir on board of a motorized vehicle comprising the steps of: a) providing a motorized vehicle having a fuel reservoir, said fuel reservoir comprising a first single coupling fitting; b) providing a portable, remote reservoir containing a liquid fuel, said portable, remote reservoir comprising a second single coupling fitting attached thereto that is complementary to said first single coupling fitting, said first coupling fitting and said second coupling fitting each being configured to provide, upon their engagement with one another, the opening of a first passage through which said liquid fuel passes and the opening of a second passage separate and distinct from said first passage through which vapor passes, within said coupling fittings; and c) engaging said second single coupling fitting to said first single coupling fitting. 2. A process according to claim 1, further comprising the step of: d) dis-engaging said second single coupling fitting from said first single coupling fitting. 3. A process according to claim 2 wherein the total amount of fuel spillage during said charging is less than 50 milliliters of fuel. 4. A process according to claim 1 wherein said second passage is concentrically disposed about said first passage within said couplings when engaged. 5. A process according to claim 3 wherein said first single coupling fitting includes a poppet valve. 6. A process according to claim 5 wherein said poppet valve includes a vent disc. 7. A process according to claim 6 wherein said vent disc is spring loaded. 8. A process according to claim 1 wherein said first coupling fitting and said second coupling fitting are each configured to provide, upon their dis-engagement from one another, the closing of said first passage and the closing of said second passage. 9. A process according to claim 1 wherein said liquid fuel is caused to pass from said portable, remote reservoir to said fuel reservoir on board of said motorized vehicle solely by the force of gravity. 10. A process for charging a fuel reservoir on board of a motorized vehicle, comprising the steps of: a) providing a motorized vehicle having an on-board fuel reservoir, said fuel reservoir comprising a first single coupling fitting, said first single coupling fitting comprising a poppet valve that includes a vent disc; b) providing a portable remote reservoir containing a liquid fuel, said portable remote reservoir comprising a second single coupling fitting attached thereto which is complementary to said first single coupling fitting; c) causing a first passage and a second passage separate and distinct from said first passage to exist between said remote reservoir and said fuel reservoir by engaging said second single coupling fitting to said first coupling fitting, said first passage being configured to permit passage of a liquid fuel, and said second passage being configured to permit passage of vapor; and d) disengaging said coupling fittings from one another. 11. A process according to claim 10 wherein said vent disc is spring-loaded. 12. A process for charging a fuel reservoir on board of a motorized vehicle from a portable, remote reservoir, comprising the steps of: a) providing a motorized vehicle having a fuel reservoir, said fuel reservoir comprising a first single coupling fitting; b) providing a portable, remote reservoir containing a liquid fuel, said portable, remote reservoir comprising a second single coupling fitting attached thereto that is complementary to said first single coupling fitting, said second single coupling fitting comprising: an adapter cover having a bore; a collar moveably disposed within said bore; a seal ring moveably disposed within said collar, said seal ring including a beveled edge; a valve center centrally located within said seal ring and configured to sealingly engage said beveled edge; and c) causing said second single coupling fitting to engage with said first single coupling fitting, said first and second single coupling fittings, when engaged, collectively comprising a connection between said remote reservoir and said fuel reservoir through which liquid fuel passes from said remote reservoir with attendant transfer of fuel vapors from said fuel reservoir to said remote reservoir. 13. A process according to claim 12 further comprising: d) disengaging said second single coupling fitting from said first single coupling fitting.
