Abstract: An electric fueling system for a vehicle that requires a metered amount of fuel comprising: a control box comprising a plurality of switches, a battery, a controller circuit card assembly, and a plurality of light emitting diodes; a flow meter coupled to the control box and to a vehicle; a pump coupled to the flow meter, to the control box, and to a fuel canister; and a housing that contains the control box, flow meter, and pump. The controller circuit card assembly has control logic such that the controller circuit card assembly manages the functions of setting the fuel level, de-fueling the vehicle, fueling the vehicle, and changing the brightness of the light emitting diodes, wherein the control logic receives inputs from the plurality of switches, the flow meter, the battery, and the pump and provides outputs to the plurality of light emitting diodes and the pump.

Abstract: An engine system includes a primary fuel source and a secondary fuel source. The secondary fuel source includes a secondary fuel with which the engine can be initially started in order to preheat the engine such that it is better able to combust the primary fuel. In some examples, the secondary fuel source is in-line with the primary fuel source, such that the first and secondary fuel sources share a fuel line that supplies fuel to the engine. In addition, in some examples, the secondary fuel source is removably attached to the fuel line, such that it can be removed from the fuel line in a relatively efficient manner.
