Cheap gas, no cleaners, and long periods of sitting can result in a surprisingly varnished fuel tank.
I've run 5 or 6 bottles of S1-1 (1 shock dose, rest maintenance doses) through my F150's fuel system with no issues. The truck has gotten periodic doses of Techron fuel system cleaner and top tier gas over its life though.
