I have a 2008 chevy silverado z71 ltz crew cab. Recently put a 2.25 leveling kit on from skyjacker and nitto terra 285/70/17 on. I am having problems with running out of fuel. Truck will say 74 miles to empty and then just shut off. Does anybody have any suggestion on what I could do. I am consisting taking the leveling kit off. Really really done want to.
