My question for the people in the know is:
How long can you store gas in a metal tank?

There is a "pure gas" station about 70 miles from me and I think I am going to set up a 50 gal or so storage / filling station out of my storage shed.

I won't have any humidity issues around here.

30 days?
90 days?

Thanks in advance
