You're missing the point. The purpose of the flow meter is to measure the output flow at rated pressure, not just free flowing fluid into a bucket. Most any pump can fill a bucket.
Adding more oil is to see if that will keep the pump primed on a hill to possibly trouble shoot the pickup tube, not the condition of the pump.
