Yeah I understand there is a big difference...but if you fabricated a cylinder like a dummy roll cage tube, an extra cross brace or something, and you could get that hydrostatically tested and stamped they couldn't really refuse to fill it. Just pull it out of the car and take it in. When our 3000psi o2 bottles fail hyrostatic testing we have to drill a large hole in the side to prevent them from being used, I can vouch that they are not made from some super thick or high tech materials.
Personally I'd just run a 20lb tank, throw some flippers next to it and say I'm a scuba diver

 

haha good idea.

 

What about that setup that Vin Diesel had in "The Fast and the Furious", would tha work. You know gut the seat and make a flip down cover for the top of the seat. And ya I know I'll get crap for it but oh well.

hey i liked it. but i bet you couldnt do it the 'right' way.

ie, person sits down and not notice they are sitting on two bottles.

 

i liked the idea of putting the wire casing over the lines.
you also have to think, how hard is a cop going to look for your nitrous bottle, and plan for that to.
im also partial yo having a custom made tamk in the spare tire, that would be cool.
hope you find something that works.

 

Why would you get a little thing like the sneake pete? Get the bigest bottle you can find! MAKE SURE EVRYONE KNOWS IT!!

I'd do the back seat personally. Not like it's used a ton in these cars anyways, and it would probably be easier to hide your line. JMO on it though.
