Try following this info, Some customers may comment that when refueling at certain fuel stations / pumps that the fuel pump shuts off prior to completely filling the fuel tank. This is not a concern with the GM fuel system but is an industry wide issue with variation in OPW 11B fuel nozzles throughout the fuel station industry.
Until the fuel station industry can replace these nozzles with an improved versions, advise customers with this concern to try either another pump and/or another fuel station. If this dosent work, post back and will advise.
