I just got a new jug from a guy who makes them and sales them on flying giants for 145.00 you can't beat it just add your battery. This is my first that I have not made myself and I have used the Sullivan pumps for years just get the gas version they make. I am curious how long you guys get running a two cell battery? My jets hold a lot of fuel and I wonder if I should just stick to running mine on a 12volt car starter box.
