How did I miss this thread?
Nice, nice, nice! Much safer than a 5gal gas can, in many ways. I bet more people have been injured by climing up in an awkward position to pour fuel than by designing and fabricating their own fueler.
I need to get rid of my 55gal air fueler. Can't afford to fill it up any more. I may start using one of those "super soakers" to squirt a gallon of diesel at a time.
