now this is the worst shortcut I have ever attempted.  Just buy the tank that fits in your truck bed along with a fill right pump, and auto shutoff nozzle at first.  Because after you buy this, you will be pissed off, and wind up spending the money you should have to begin with number one....kit comes with a s***ty hose that gas eats through in the first week.  This is after you have to find help getting said s***ty hose over the flange of both the pump and the nozzle.  Even if you manage to get this done yourself, you still pissed off because you just wasted an hour and your hands and fingers are blistered.  The pump itself is great.  Everything with it will definitely let you down.
