Getting the boat ready for the upcoming fishing season. I want to drain my tank and put fresh gas in. My tank is not accessible, and there appears to be a long black tube that runs from the cap to the tank that the gas travels through. Gas cap is in the back of the boat, and I'm thinking the tank is situated near the front. Suggestions on getting the gas out? Somebody told me all tanks are supposed to be accessible somehow? Am I perhaps missing an access area to it. If not, what tools will I need. Thanks!
