Storing 400 litres of gas in my area would cost about $250 USD for 2 new 55 Gallon barrels, maybe more if you want a nice pump. I had a 10,000 gal tank put in

Storing 400 litres of gas in my area would cost about $250 USD for 2 new 55 Gallon barrels, maybe more if you want a nice pump. I had a 10,000 gal tank put in for agricultural diesel, and that cost about $5,000.
