200psi rated tanks

it's all good for those that do it, but who knows, YOU could be the one who gets the slightly less stable tank and then what happens when 200,400, or 600+psi pops out of 5 or 12 gallons in your vehicle?

I just hope nobody gets hurt.

im runnin two 3 gallon tanks from suicide and i run both up to 200 psi with no problems

ive always ran 200 psi into the 150psi tanks...no problems

So whats so great about the 200psi E tanks??? I've never had a prob with 150s.

Or you can make one,This is about 5gal.

I don't think square or rectangular tanks are good high pressure. By design they aren't are strong as a cylinder style tanks. The flats ends and the seems are weaker. I'm an engineering student and have had this discussion a few times, but that my opinion (I guess)
