I have a chart on page 141 in my book, "Racing Engine Builder's Handbook". If you don't have a copy of this great book

following are some specifics. As was said, the dash number is pipe size in 1/16". ID for -10 and -12 AN hose is 9/16" and 11/16", respectively. I think Carroll Smith covered this subject in depth in his book on Racing Hardware.
Check out this sight for loads of good stuff from coolers, to AN fittings to Fuel filler caps.
