Fuel Pressure

Vehicle lost fuel pressure. Dropped the tank and found the rubber on the hoses gone. Replaced fuel pump, hoses, filters. Still no Pressure. Disconnected the lines and tied test gauge inline and have 80psi at the fuel rail. Leaks to 60 over a day. Still no pressure. changed the fuel pressure regulator and still no pressure. I cleaned the fuel rail out and it has no clogs in it. Any other suggestions? I am leaning towards the new pressure regulator not allowing the fuel through. I have ordered a 2nd one but will take a week to get here.
