The Spa Flo II and Hi Flo II faceplates have the same number molded into them. E128519 IS NOT THE PART NUMBER. As you can see, they have different suction fittings. The rear of the faceplate also shows the same numbers 311-2170 and 311-2160. Be sure to chose the correct faceplate when ordering on http://www.waterwayparts.com
