Long ago you could buy #2 (nothing reeks worse than high sulfur #2) when the price was down at a cash discount. I doubt if there are any deals any more. People would hire me to install a pair of 330 gallon tanks, tanks made to fit through a door. 660 was the maximum indoor storage without a fire wall. So some people built a bunker and I happily put four of the heavy things in a spillproof contained concrete cellar hole. They poured an underground stinky shed outside the foundation, very clever. 1000 gallons would get most Yankees through to when oil was cheap again. I remember when #2 passed $1.00 a gallon, and Yankees refused to buy it, they burned wood that winter.
Other people had different ideas, but for me each 330 (or 275) had it own whistle and fill
two tanks max teed to a two inch vent: four 1.25" fills; two 2" vents. There will be no leaks.
Once upon a time, very commonly two tanks were piped in series, one fill, one vent. The modern truck's pumps could and did easily split the end weld, loosing a couple hundred gallons of stinking oil into the cellar. I was spill response, strong stomach, strong back.
Once upon a time, people buried 1000 gallon single wall tanks in their front yards, a disaster waiting to happen. Fairbanks has a generation of buried single wall 1000 gallon tanks, they were good tanks, tarred and buried in sand. They corrode from the inside out, from the sulfury bacterial sludge. They are all gonna leak, someday.
The last two tanks I buried were a pair of 10,000 gallon double wall with fill containment and intersticial alarms, cost most of $100k. The tank insurance will pay for removal in 20 years. If you want to burn 30 gallons an hour, you need a lot of 30 gallonses.
Truck would bring 9300 gallons per trip, $26,000?
