Hi Laurie,
I got an old trailer(donated from friend) and re-sprayed it, mounted a 200lt Ex Avgas drum (free from depot) on it permanently, and use a regular rotary hand pump(about $150) that delivers 0.6lt per rotation. I just drive to the local servo and fill it up and keep it in the hanger. I use a jumper cable for earthing. Easy option. I carefully mounted the drum in the middle of the trailer to balance it and make it easy to move it around by hand.
a (rather poor!) photo attached.
cheers
