It's pretty dangerous trying to flow test a high pressure pump to me like that. I had an LT-1 EFI powered car and it had an Aeromotive A-1000 pump. It had a Paxton pump previously that failed the first time I raced the car. I replaced it with and The Aeromotive was exactly the same. With 24lb injectors I ran some 10.50's in good air back in 2006. The same car has run 10.20's and probably still has the same pump and fuel system. I ran 50lbs pressure and experimented with higher pressure once....It slowed down. I have an all Aeromotive fuel system in my dragster and their stuff is excellent. The design of that pump has magnets epoxied to the outer housing. It has brushes and an armature. If your reading very low pressure and voltage running the pump I would pull the pump out and I would take it apart and inspect it or bench test it. You could power it and pump a fluid less volatile than gas.....mineral spirits.....
