Scott I understand your consern. Does anyone really put that much preasure on them? The guys I get my imfo from all all in the Naval Medical Reserch Facility. They build all kinds of WILD $hit. One of the guy's there said "If you put 4lbs in that sucker it will unzip itself". he's a pretty sharp guy and has fooled with this stuff a fair amount.
Here's a quote from another guy who builds fuel tanks.

Warthog...
Yes 3 lbs. is ALOT, you dont need that much air at all. Just fill up the tank till it bulges a little bit, don,t over fill it at all. Use a soapy water mixture in a spray bottle to find leaks. Wow, Stainless is definate overkill. That tank will break your back. Stainless is ok for a tank but usually for hundreds of gallons. A 70 gal.
tank could have been made of aluminum and weighed less overall. The gas
pickup should be no less than 3/8ths dia. tubeing. Any less will starve your
motor and stall eventually. Do not put any back flow devises on your gas line
they tend to starve an engine as well. Use a good recomended cartrage in
line filter. The vent, nothing less tan 5/8ths hose, anything less will make it a
hard slow filling tank. Try to make your gas fill tube a straight run to make it a faster filling tank, any bends or 90 degree fills will drasticlly cut down filling of the tank. Bet you'll never try another tank again, only if you must.
Good luck...
