I had problems purging the air from the IP, so I removed the ball and spring to allow the fuel to free flow when the ball valve is open. I have not had any problems with air since.
When I get the new spring in, I am going to put an adjustable fuel pressure regulator in the return line, with the valve for a bypass option.
