Saving a strange hand crank diesel/oil pump.

Origins in early fuel dispensing (1880s–1920s) Kerosene pumps: The ancestors of today's hand pumps were developed before the automobile. In 1885, S. F. Bowser created a pump to dispense kerosene from barrels in general stores. The device was hand-operated with a crank to deliver fuel into portable metal cans. Adaptation for vehicles: As "horseless carriages" became more common in the 1890s, Bowser and other inventors modified their designs to directly fuel cars. Early pumps often required an attendant to count cranks to determine the volume of fuel delivered. The "blind pump" era: Around 1915, manual gas pumps were common, but many lacked visible gauges. These "blind pumps" made it difficult for customers to verify the amount of fuel they were receiving, leading to uncertainty. Transition to visibility: By 1918, visible pumps with large glass cylinders were introduced. Attendants would manually pump fuel into the cylinder, and the customer could see the volume before it was dispensed into the vehicle's tank.
