well maybe i had not explained before that when i had bought the new "motor" I had thought that I had bought the works. I did not realize at the time I purchased it that it was only half. so any ways the "pump" part of it after being tested is no good. so, I have since acquired another set up, pump & moter, after tested does work, but now it seems to me.... that the piping is the wrong size... bigger then what the new system was made for.
