Yep this is a great approach...thanks David you beat me to it. If you have a motor where you can't tap into the fuel tank directly, you can still have the remote tank with hose and bulb pump. The hose will just be stowed - with the free end plugged, or a small nylon or brass on/off valve on it - until you need to add fuel. When you need to add fuel to the motor's tank you can just remove the cap, put the hose in, and pump the bulb. No need to lean out over the stern with a jug or bottle and very low odds of spilling gas. I add this because most new small outboards have the kind of gas caps where there is an inner shell and an outer shell, and they 'click' when rotating to tighten. The outer shell of the cap is rotating around the inner shell. So you can't drill a fitting thru the cap, because it will have to go thru both pieces of the cap (inner and outer) and the cap will no longer work as designed. Older outboards with simple one piece solid plastic caps, as David says you can put a connector fitting thru the cap. cheers, John On 11/5/21 6:57 AM, David Grah via montgomery_boats wrote:
We use a 3.5 gallon (sometimes a 6 gallon) plastic fuel tank secured in the back of the cockpit. We use a rubber fuel hose with a rubber bulb pump to pump fuel from the plastic tank through a modified fuel cap on the motor and periodically fill the tank on the motor. The cap is modified by drilling a hole in the middle of it and screwing in a fitting to take the rubber hose. We usually get a couple of hours on a tank in the motor so end up pumping it full every hour or so if we are motoring continuously. Usually takes 10 to 30 squeezes of the bulb to fill the tank back up. It is a system I learned about in this forum and works great. David GrahBishop CaliforniaMontgomery 15
