That fuel box drives me nuts. Can be quite annoying in long distance races if you haven't done much long distance practice lol. Which I never do. Practice for me is always about finding more speed. Then when it's race time, it's like.. err, shit, how much? Then just random guess, hope for the best. Grand Am races are typically the same for 50 minute races. 80 minutes I'm always doing 1 stop regardless, and just guess how much to put it when the time comes lol.
