Hello all. 1st post for me. Well I have a 2004 F250 5.4 Gas. I am having a problem with the fuel guage. I fill up and it reads 1/8 tank lower than full. But when I get down to a 1/4 tank (im thinking that im still a 1/8 off. But when i fill up it only takes 16 gallons. I have a 29gallon tank. Any help would be greatly appreciated. Thanks
