Very disappointed with the quality of the plastic used for the tank. The original part is made of aluminum, as is the valve body attached to it. When I attached the valve body to this motor and reservoir almost all of the threaded holes broke. Attached is a photo where all the cracks are. It doesn't leak, so I decided to use it anyway. Additionally, not all of the screw holes line up for the mounting bracket, particularly the top one, and perhaps most importantly, where my bracket has a screw hole in the middle, this one has two, one on each side. See photos. Otherwise I installed it, the motor solved my problem and works fine.
