I don't think so if it's the in tank pump. Pumps get weak over years and lose some of their max ability to pump as they did when new especially the in tank pumps. Below a certain level is asking for trouble and things can be boom if one gets greedy with the boost. External pump adjustibility, possibly?
No need to post a pic as I know which you have now. As Onalky87 mentioned, if your kit has a pressure gauge by the bottle, have a friend verify the number it climbs to when you press prime on the controller with car running. I'll look for the archived email info from Steve when I had the same problem as to minimum value you want to see from the pump PSI.
