fuel rail and regulator

[john breit]

I have a 2000 gt / naturally aspirated. I was changing the fuel regulator and there were 2 listed for my engine and neither of them were the right one. Ends up it is a regulator for a supercharged.
I'm wondering why I would have fuel rails and regulator for supercharged on my engine. And if it could be a problem.

I used the fpr from autozone. It is part number 800-319. It is a sorenson. Fit like the stock one.
