All I can say is that it is a pretty risky proposition to siphon gas like that. I know that I , or most people I know, wouldn't take too kindly to coming back to find some d-bag stealing my gas. They better hope they can get away fast, and that goes for me seeing anyone's truck in the lot being messed with. My buddy had his trailer stolen while out on the lake, and all I know is there is someone out there with whole lot of bad karma coming their way.
