David,
That is one reason I was never to interested in drag racing. Lots of travel, money, and one bad run and you are through for the day. At least in road racing if you aren't leading after the first lap you don't have to load up and go home. I thought the 22.75 gallons per run was about right from what I hear them say when I do watch the drags. These two pages they published on Schumachers top fuel dragster really had some surprising statistics. I never dreamed it took that much power just to run the blower.
