I'm all over that!!!!!!! how much did it cost? I got online to check the price and you had to e-mail someone so i thought I'd ask you the price. Let us know what your mpg for a whole tank is. How in the world were you getting 24mpgs in the first place? About 2 years ago my wife was driving a 99 Expedition and was only getting about 11 or 12 mpgs. My impression was that Fords suck the gas. Looks like if you got a 10mpg diff one way and 3-4 going the other, you net 6.5 mpg gain.
