Here's one to take for interest sake (definitely not a recommendation and bound to be controversial) on a trip last year through Victoria I spotted this set up. Uses a $95 ebay diesel/kerosene pump that was being regularly used solely for 98 and avgas in a Cessna. Mounted on an old shopping trolly his jerry cans either in the trolly or ute and Anderson plug on the aircraft to power the 12v pump. Apparently 20l empties in 30 secs, no leaks and works well. Pump, hoses and auto nozzle part of the package.
