I recently added this to my trunk just in case I run out of gas. I can either get gas from another bike or really any other vehicle. I keep a gas can in my truck. I hauled my TG to Sturgis this year and on the way home I came very close to running out of gas in my truck. Yes, I could of unloaded the TG run to the gas station, get gas and bring it back. But, I thought what if I had one of these and a gas can? I had plenty of gas in the TG. So, I bought the pump and my truck will always have the gas can in it. I may even add the small gas you can stow in the Tour Pack or trunk.
