I have had a 306 for a year. Everything I read about fuel and filters states that you must keep checking for water. My boat has a stock Racor 110A fuel filter which has a metal bowl on it. The only way to check for water is to lay on your back and use the drain plug. O.K. I can do that! My question is, If you open the drain plug will the oil and water drip out slowly and will the fuel be sucked from the tank so that there is no need to prime the filter. If not,why even have a drain plug? If you must prime can you insert a bulb primer in the fuel line between the tank and the filter. You Know, the outboard type primer.
