I have a 275 gallon plastic tote with the wire frame around it sitting on top of my shop in my pole barn. I have had it since 2004 and get it twice a year by my fuel delivery guy. I use gravity to do all the work. I picked up a 2' piece of 3/4" fuel hose that goes from the tanks ball valve to a filter then a 10' piece of 3/4" fuel hose going nozzle. Have about $50 in the setup and its been trouble free.
I do put a gallon of Howse (my preferred) or Power Serve when its filled along with enough biocide to take care of things. Never a issue.
On top of the tank I built a vent out of a piece of PVC and a 180 deg piece with screen wire zip tied over it.
