Query: works great

I wanted something to siphon the gasoline from a five gallon tank on our dock to our jet skis in the water. The tanks are heavy and cumbersome when trying to fuel in waves.I watched the video that was posted, and then tested the siphon by sucking the water out of the base of a basketball system we wanted to get rid of. It worked really well.I selected this simple design, because I saw the battery operated pumps actually pump fewer gallons per minute that this simple manual siphon..... without batteries and without the noise.
