How to Repair the Windscreen Washer System on the 1966 Lancia Fulvia

Model: Lancia Fulvia MK 1 - Years 1965-1976
Part: Windshield wipers

Let’s see how to repair the windscreen washer system on the 1966 Lancia Fulvia: the manual pump has no internal valves, and the system requires non-return valves and pipes. Therefore, check the existing valves, ensuring that the non-return valve in the pipes allows flow in only one direction. If necessary, replace it with a new one, or clean it as shown by the YouTuber, using a thin copper tube to clear the blocked nozzles. These are adjustable with a flat-head screw. The valve has only one correct direction: the one that prevents fluid from returning to the reservoir on entry, and on exit prevents fluid from being sucked back into the pump from the nozzles. Perform a final test: pump manually and hold before releasing for optimal pressure. Adjust the height of the nozzles.
