8. This quick connect line pump has a male "Yamaha" fitting on one end and a screwed on stopper on the other end. We can now pump fuel from either tank and have the volume measured by the fuel management meters. We use this to fill our 1000 Watt "Honda" Generator and our 2 hp "Honda" tender motor. Now we don't need to carry a portable fuel container on board. We could also pump fuel to someone else if need be or empty our tanks.
