The charts are identical for both fuels.

At 0.7 g/ml, the light end, 5.836 lbs/gallon,
At 0.8 g/ml, the heavy end, 6.671 lbs/gallon

Quite a range.

Hm, I just read all the other replies, and I'm
wondering how my number differs so significantly.

1 gal =3D 3785.6 ml (cc) according to what I find
A gallon of pump gas is 5.6 gallons.
60 minutes in an hour, of course.

So for 1 lb/hr, ((1 / 5.6) * 3785.6) / 60) =3D 11.27
cc/min.  What am I missing here?
