Trick fuels and Race gas storage


I had someone ask me about this fuel and at one time I thought it to be one of the fuels Eric Gorr recommended. Whats the best bang for the buck in their line for a stock 02-03 CR250. I have an unopened barrel of c-12 so for the fuel storage question. I have known fuel to be stored under nitrogen to prevent degradation and evacuated by applying nitrogen pressure and pushing it out a hose. Since this seems to be the expert room for race gas what pressure are these drums rated for or what would be the highest pressure in a closed drum asumming the fuel has reached 120 deg F. I could always pressurize one with water and see at what pressure it splits or calculate it ( I'd need to know the yield strength of the material ) but thats not why I joined the forums. Thanks in advance.
