1. Yes, the raised tank is for gravity fueling and therefore no pump required. I don't know what the flow rate is but it's faster than my hand pump for sure!
2. The stand isn't meant to be moved around much. I can lift it with the tractor and pallet forks, but I don't attempt to move it when it's full of diesel. So, it will stay in one place between fill ups.
3. I wouldn't store gasoline inside a building for sure. However, this tank has diesel in it and is under a lean-to cover. Check with your local fire department and your insurance company if you think there might be an issue.
4. When I was building my tank stand, I asked the local fuel delivery if they wanted a ladder welded to the tank. They said no, *we just back the truck up to the tank and stand on it. Sure enough, the delivery truck had steps built into it just for this purpose.
It's funny how some places outlaw things like overhead tanks and in other places, it's the norm. I'm proud to say Texas doesn't have too many petty rules (at least not yet).
