I searched but can;t find this- I have a 1990 Black Max 135 on a 1990 Sea Ray -new to me boat-getting ready to start after winter and discovered primer bulb (Moeller) is cracked-even got some fuel on my fingers as a bonus-but I don't know the size of teh bulb to get to replace-I have seen a universal advertised to fit 3/8 and 5/16-and any advice about removing it?
