Where does the gas tank go?
That depends on the type and size of the engine. If it is a smaller type, then it might be attached to the engine and you can fill the tank up at the engine. While this is the easiest and cheapest alternative, it also mean you might have to stand on something while in the boat to refill your tank. Remember that the engine is going to be 5-6 feet in the air and the tank is generally on top of the engine. If you have a larger engine, then you will be pulling the gas from an external tank. My boat uses a typical 6 gallon plastic boat tank and uses a Puralator low poundage fuel pump (1-4 lbs available at O’Reilly auto parts) and a Puralator low poundage regulator. The regulator is necessary because the fuel pump is not adjustable. Too little and you starve the engine and too much and you flood it. It is also nice to be able to tweak the mixture with the regulator. Keep in mind the location of the fuel tank. Gas is fairly heavy, so try to center the weight or balance it with something else
