sorry, i believe you are the retard.
A quick google search reveals that 68 cubic inches of air weighs about .003 lbs, at atmospheric pressure, or 14.7psi. Now, if you fill your tank to 4500 psi thats approximately 306 times atmospheric pressure. Multiple .003 lbs by 306 and you get about .9 lbs of air. Almost a pound. Pretty significant you ask me.
If you want to check me here are the sites i used.
