Con :
Install was not the 10 minute job I had planned on.
I believe this pump is represented as being a substitute for 137108000.
From what I can figure the 137108100 discharges to the right side whereas the 137108000 (which I needed) discharges to the left.and the mounting base is different.
Used the mounting bracket from my old pump to avoid drilling. Turned the orientation of the  pump head and check vlave. The modification is not rocket science but could deter individuals that are not mechanically inclined. Just have to make sure that the pump head goes back together properly so do not get leaks.
Hope the modification info is usefull to others.
I would purchase agian
