Fuel pressure dropping while driving and under acceleration to zero at idle runs 4 lb electric Blue

Thanks for the reply. I will reread through that information. As I said in my last post I took the fuel pump out of the equation. I had a brand new fuel pump that I installed on Saturday with new electrical fittings and a brand new pump. And it done the same thing. It would keep pressure as long it was. It was idling as I give it gas above 1500 RPM. The more I give it gas the more the pressure would drop
