Re: Where is the fuel rail
On my TPI the schrader valve is on the fuel rail on the passenger side. I've seen it also on a 2001 GMC with a 4.3 in the center of the engine towards the back. It is always on a metal fuel line somewhere. Have not had a chance to search a 3.1 b4. But if it is there, you should be able to find it on a fuel line somewhere. Using a flashlight doesn't hurt when searching. I would start at the forward most fuel injector on each side and work your way back.

Re: Where is the fuel rail
This is where the nipple to test is...look around here.
Sorry I don't know how to describe the exact location..and can't take a pic at the moment.
The pic was found with google and the engine isn't mine:
