	My question is what specfic gravity of fuel are "They" using as a
standard and what are "They" using for the weight of the fuel?  I have seen
some using anywhere from 5.5 lb to 6 lb. per gal.

Sorry, I have to ask why would you flow an injector at 85%, then multiply by
.85???   Wouldn't it be easier to flow it at 100% then multiply by 85%?
