Windscreen Washer Bottle Hose 

The windscreen washer bottle hose is a direct replacement hose designed to connect the washer filler neck to the washer reservoir on the Porsche 928.

Over time, original washer hoses become brittle, crack, or split due to age, heat exposure and constant contact with washer fluid. A deteriorated hose can lead to leaks, slow filling, or washer fluid escaping before reaching the reservoir.
