a buddy of mine filled up his 03 (34gal tank) his fuel light just came on, he filled his truck (2 transactions) added the total number of gallons from the reciepts 37.78 gallons!! i'm not sure but i dont think 3.78 gallons can fit in the fill neck?? and he should have had at least 4 gallons in there when the light came on... the manager said when the air temp goes from high to low, low to high it throws off the calibration on the pump! they gave him a 10$ gift card. just a heads up? i'm computing by hand from now on...
