A petrol pump is a facility where fuel, primarily petrol or diesel, is dispensed into vehicles. It typically consists of one or more fuel dispensers, which are machines that measure and deliver the fuel. Customers drive their vehicles to the pump, select the type of fuel they need, and fill their tanks. In addition to fuel, many petrol pumps also offer other services, such as car washes, convenience stores, and air pumps for inflating tires. They play a crucial role in transportation by providing the necessary fuel for cars, trucks, and other vehicles to operate efficiently.
