Hey Cody, my concern is if they didn't change the tank size rule then maybe they should and require a minimum that is closer to what everyone is running. If they don't someone will come out with a 59 gallon tank soon since that would be big enough now and that would obsolete all the bigger ones we run. That size must be left over from the 4cyl. offy days although I'm not sure what those cars had for sure. USAC really ought to raise that minimum, of course they now allow all the cage body work like the sprint cars so maybe they want to run smaller tanks like them too, even though not one fan likes small tanks. I would also like to know how much this fuel will cost next year???? Thanks for your info, Mike.
