thats why i was planning on adding one now, to remove the air that is
probably building up in the system. There is another way I thought of that
air could get into the injection system: Through the fuel return line. I
have been letting the fuel return line drain into an empty bottle with no
seal, perhaps air is leaking back into the system through the line?
