I really need help...PLEASE. I performed a routine primary fuel filter change for the start of the season, like I've done on all of my boats with success, until yesterday. My Volvo MD22 is giving me fits. I can not successfully expel the air from the lines. I'm not sure, first of all. where all of the bleeder ports are on the Volvo. I purchased the boat without a Volvo service manual, and have no clue as to there where abouts. Nothing is obvious. I had so much air pressure in the lines I had fuel coming out of the vent (the tank is full). Any website, archive or direction would be helpful. Plan on calling a mechanic but thought I would give my fellow boat owners a try first.Thanks in advance.Mike
