A computer-implemented method of supplying a fuel gas to a fueling system, wherein a processor is configured to control a number of valves in the fueling system to allow or restrict gas flow to perform operations comprising pre-fill inerting the fueling system , wherein the processor controls the number of valves to cause a purge gas to be supplied to a fuel gas supply manifold by selectively fluidically connecting a purge gas supply to the fuel gas supply manifold of the fueling system ; and cause the fuel gas supply manifold to be selectively fluidically connected to a vent manifold ; leak-checking the fueling system , wherein the processor controls the number of valves to cause the fuel gas to be supplied to the fuel gas supply manifold by selectively fluidically connecting a fuel gas supply to the fuel gas supply manifold ; charging a pilot subsystem of the fueling system with the fuel gas, wherein the processor controls the number of valves to cause the fuel gas supply manifold to be selectively fluidically connected to the pilot subsystem ; filling the fueling system with the fuel gas, wherein the processor controls the number of valves to cause the fuel gas supply manifold to be selectively fluidically connected to one or more fuel gas storage vessels to flow the fuel gas from the fuel gas supply to the one or more fuel gas storage vessels via the fueling system ; and post-fill inerting the fueling system , wherein the processor controls the number of valves to cause the purge gas supply to be selectively fluidically connected to the fuel gas supply manifold . pre-fill inerting the fueling system , wherein the processor controls the number of valves to cause a purge gas to be supplied to a fuel gas supply manifold by selectively fluidically connecting a purge gas supply to the fuel gas supply manifold of the fueling system ; and cause the fuel gas supply manifold to be selectively fluidically connected to a vent manifold ; cause a purge gas to be supplied to a fuel gas supply manifold by selectively fluidically connecting a purge gas supply to the fuel gas supply manifold of the fueling system ; and cause the fuel gas supply manifold to be selectively fluidically connected to a vent manifold ; leak-checking the fueling system , wherein the processor controls the number of valves to cause the fuel gas to be supplied to the fuel gas supply manifold by selectively fluidically connecting a fuel gas supply to the fuel gas supply manifold ; charging a pilot subsystem of the fueling system with the fuel gas, wherein the processor controls the number of valves to cause the fuel gas supply manifold to be selectively fluidically connected to the pilot subsystem ; filling the fueling system with the fuel gas, wherein the processor controls the number of valves to cause the fuel gas supply manifold to be selectively fluidically connected to one or more fuel gas storage vessels to flow the fuel gas from the fuel gas supply to the one or more fuel gas storage vessels via the fueling system ; and post-fill inerting the fueling system , wherein the processor controls the number of valves to cause the purge gas supply to be selectively fluidically connected to the fuel gas supply manifold . <EOS>
