Genuine Lucas screen washer motor/pump.
Often deceased through lack of use this little electric pump sure beats the old fashioned hand pump on early cars. Replace yours or upgrade your car with one of these genuine Lucas pumps.
Please note this pump must not be run dry there must be washer fluid in the system (primed) before activation. Running dry will over-speed the impeller and voids any warranty.
Mounting holes are approx 39mm apart
