Did you also use the GPS to verify the distance traveled?3:31 gears
31 inch bfgs
weight about 3500lbs
around town and highway it dosen't seem to change
rpm at 65 was about 1800
4bta with an alternator and ps-pump
I used a gps to verify the speed...
Both times were until I absolutely could not get any more in. Fill, let foam die, fill, more filling, even more with the foam until I had fuel right up to the cap both times....Did you fill it up the filler neck before and after the trip - or did you just fill till the pump shut off?
