have just got into boating and with that forums so please be bear with me. Ihave a nercury classic 50 with 6 gal. portable gas tank and oil injection tank. Having trouble getting a hard prime bulb. Replaced bulb, still same thing.Bought boat and motor user and Ithink it is a 1987 model. It is between the oil injection tank and engine. Is this correct or should it be between gas tank and oil tank.<br /> Thanks
