You will have to figure the storage pressure by trial and error. 40psi
at 50f will give you 4.5 volumes of CO2 - explosive by any measure!

If you have a british style beer you want ~2 volumes. At 50f
the equilibium pressure is 12lb I store and deliver my beers at 48f and
around 15-18lb. A little fizzy for english, a little flat for german.
No big, I just pour from a great height to kill the carbonation. It
mostly works out in the end. For german beers you want around 2.5-3
volumes which works out to 18-24psi.

The table I am working from comes in the fall 1990 Beverage Peoples News.
Their info line is 1-707-544-2520 (greater fermentations of Santa Rosa).
Perhaps they can give you a back copy? It also has a good discussion of
force carbonating your beer.
