Can anyone tell me where the fuel pressure regulator is located? 2003 SLE. Picture?

2003 Pontiac Bonneville - GM03313H01 Fuel Injector Rail L362HX69
Number 3 in on the fuel rail. Hope that helps.

Thanks guys. So pulled off the vac hose and did not see moisture but definetly smelled like gas. Sounds like I may need to change it? Looks like I remove the retaining clip and just change out.

Did you leave the hose off for a while, and see if any gas comes out of the regulator?
If the diaphragm is ruptured you should see a little gas come out after a while.

Replacing it is easy, just remove that clip and wiggle it up and out.

Here is a decent youtube video that I found the first time I had questions about my FPR.

Thanks for digging that up William. This is a really good video on the 3800 FPR.

Very welcome Mike, always happy to help!
