Manual MINI windshield washers were the common in the 60's. The pump works on a simple internal diaphragm to create pressure for squirting the water through nozzles, providing more than sufficient volume and pressure to allow for cleaning. With a small windshield this might not seem important until you consider the need to wipe off the mud or grime as you drive. These chrome nozzles are two in one housing, and are screwdriver adjustable for height. Sold individually.
