So today on mad scientist theater, we'll be combining a car or truck's fuel tank and pump with a pressure washer from Home Depot with a Road Flare.
You'll need a couple of garden hose fittings and a 12 volt battery, but if you're mounting this in the bed of a Truck, the 12V from the vehicle's electrical system will be fine.
