guess you have the 15 gal. tank? mpg's are effected by a lot of things but doubt replacing those parts will have a positive effect. i would clear the codes and start the fuel trim relearn process again. air up your tires to at least 35psi, make sure your air filter and plugs/wires are in good shape, lose any excess weight in the truck, and go from there.
i'm getting low to mid 20s mpg average depending on the ambient temperature using crap 87 octane ethanol laced gas.
