I believe there might not have been a problem with the pump. Once I realized from tips here on FB that I wasn’t putting enough pressure on the pump arm in initial pump bench test & when I did it showed good vacuum & Pressure on my gauge.the first install that caused me to question the pump was probably the rod not seated on pump arm as Allen suggested. But thinking the bowl wasn’t sealed because I had taken the bowl off & re-installed after in position ( PIA ) to access mounting hardware in cramped quarters. I changed install sequence trying to make it less of a PIA by putting the stand in position first then seeing the rod thru the side mount hole in the stand was able to insure the arm seated in the cylindrical containment seat & was engaged correctly before installing pump mounting hardware.
