Not nessisarily a cheap set up, but I have an 8 gpm flow rite pump. It's rated for gas or diesel. Not super heavy has pretty long cord for power. Have a water blocking type filter on it. 12 volt. Works pretty well. 3/4" hoses on it. I should really get a gas pump style nozzle for it, but I use it to transfer in and out of a 275 gal tank. Gas nozle would get old to hold open imo. It's a bit slow for larger tanks. I also have this "heavy oil pump" it was made to pump oil in and out of a Komatsu powered generator. It's really fast, but 24 volt, and quite heavy. Used it a lot when I did road work. Every thing was 24 volt and held lots and lots of oil. Made life easy. Now I just hate to use the heavy bugger. I have a poly 55 gal drum rigged up with some 2x4 and metal straps to toss in the back of the truck. Not ideal, and I only fill it to about 40 gallons. But it works. Just hook that little fill rite up to the bottom hole in it. Open the valve and pump into whatever. It's real handy when I'm not around the house and working in the woods, or over at my mom and dad's place. One day I'll get a real transfer tank.....
