Do you have a separate transfer pump and primer pump? Usually air will leak between the tank and the first pump, after that it will be under pressure.
You usually won't find a suction leak by pressurizing the line, use clear tubing to see the bubbles if replacing rubber hose and the new primer pump don't fix it.
