What should a guy expect a mechanical pump to do when he puts the patriot pedal to the freedom floor? Mine bounces around 7-9 at an idle (40gph unit) and drops to 4 under load. I need to drive it a little more to make sure it continues to hold at 4, but if it does can this be considered normal for a mechanical pump? Or should it stay closer to that 7-9 range it operates at at idle? Yes, 7-9 seems a bit high but it's what the pump does out of the box with no regulator. It's a China made Delphi pump.
