The 16 pounds of fuel you would save for race weight isnt worth the two gallons of miles i could get out of the fuel if i mount the sump forward on the tank, and were traveling on level ground , i could easily get 40 miles out of it, that extra gallon or two is the whole reason i went with a sump, that and it is easier on the air dog to be gravity fed.
