I previously owned a '96 STS and had the nylon fuel rail replaced with the stainless steel rail under the recall. Yesterday, I decided to change my fuel pressure regulator on my '99 STS due to some difficult warm starts, and lo and behold, I find a nylon fuel rail. Does anyone know what is different between the '96 rail and the '99 rail that would make this one okay, but not the '96 one???
