Abstract: A compressed natural gas fueling system includes a frame arrangement with at least one tank disposed therein and an inlet that can receive a compressed natural gas fueling nozzle to fill the at least one tank. The fueling system can be attached with and supported by frame rails behind a cabin of a vehicle such that the inlet is positioned above the frame rails.

Abstract: A filter assembly for a vehicle can be configured to be in fluid communication with a source of compressed natural gas and coolant for an engine. The filter assembly, when so arranged, filters the compressed natural gas and routes the coolant there through to warm the filter assembly.

Abstract: A manifold assembly includes a manifold block having a female inlet, at least one outlet, and a gas passageway between the female inlet and the at least one outlet. The manifold assembly further includes a check valve that is sealable against the female inlet and arranged at least partially within the gas passageway between the female inlet and the at least one outlet such that in the absence of pressurized gas within the female inlet, the check valve is sealed against the female inlet, and in response to the introduction of pressurized gas within the female inlet, the check valve recedes from the female inlet to fluidly connect the female inlet and the at least one outlet.

Abstract: A compressed natural gas (CNG) fueling system includes a CNG reservoir that can be mounted to a vehicle, a sensor arrangement that can sense an environmental condition in a vicinity of the vehicle and a condition associated with the reservoir, an electronically configurable display that can be mounted within a cabin of the vehicle, and an electronic control unit (ECU) operatively arranged with the sensor arrangement and display. The ECU generates output for the display based on the sensed conditions to provide information about the CNG fueling system.
