I don't use a tank. I have a fuel station 9/10's of a mile from my house via the road, less if I cut thru my neighbors property. I drive up there when I need fuel. If I am going after fuel for the lawnmower, I usually tank a 5 gallon can or two for diesel. I had a 4'x4'x2' aluminum one, didn't use it enough to justify it, so I sold it for a lot more than I paid for it. There are times when I miss it. In case of emergency like a hurricane, I have 200 gallons of fuel in a truck sitting in the driveway that I can use, so that helps.
