Ditto on the transfer pump setup, if I can find a fuel cell or boat tank that's what I'm gonna do too. I have a grip of small electric fuel pumps that I keep for truck spares and was planning on semi-permanently mounting one between the tanks, running a switch to the dash and just transfer fuel when I need it. I planned this mostly for use on longer hunting or road trips cause I usually take a few cans anyway and this would be a much safer and more convenient way to fill up. The same basic style pump I'm using can be had at Kragen for about $35 I believe, little black plastic, but if you buy that one get a thick rubber grommet and put if between the pump and whatever you mount it to, they're pretty loud but that damps the sound pretty well. It's easy to wire, just ground to the frame, run a fused hot lead off battery to switch and a wire from switch to pump.
