Question I have is regarding the vapor seperator on my 92 Oceanrunner. When I squeeze the primer bulb to build pressure I can hear a fluttering noise from the motor. I have narrowed it down to air releasing from the rubber tube that connects assembly that contains the primer solonoid. The tube runs from there into the air box that covers the carbs. Is this normal? Bulb never seems to pump up rock solid unless I hold my finger over the tube.
