I can't find it now, but I came across a thread or two about the gen 2 fuel gauge and how to reset it when it goes wacky. I have tried the procedure a couple dozen times now and it just doesn't work. My gauge shows a lot more consumption than there really is - will go down to 1 dot when it is just 6 gallons down. Please recheck the reset procedure or post the actual TSB it came from.
