overall 99 gmc has been an exceptional truck - first use high end off road shocks not dealer nor parts source pieces fuel will try a fuel pressure adjuster not a factory pressure regulator. otherwise great power and exceptional fuel mileage even at 12+ years and still going strong. been a great truck.
