A fuel bowser is a mobile fuel - storage and dispensing unit, typically used for refueling vehicles, equipment, and machinery at remote locations or in areas where fixed fueling infrastructure is unavailable. Fuel bowsers vary in size and capacity, with some capable of storing a few hundred gallons and others holding several thousand gallons of fuel. They are equipped with built - in pumps and hoses for convenient fuel dispensing, along with metering devices to track fuel usage accurately. Safety features such as spill - containment trays, grounding cables to prevent static - induced fires, and lockable compartments for security are common. Fuel bowsers offer flexibility in fuel distribution, making them valuable assets in industries like construction, agriculture, and mining.
