VZ GTO. VS LS1.
The fuel pressure reg is located on the back of the drivers side fuel rail. The return fuel hose back to the firewall is connected to it. I cant remember for certain, but of the VT-VY ecotecs which run the gold coloured steel fuel rails, I think the Vt was the model where the reg is sealed in this and is not removable. If this is the case, A whole new fuel rail is required in order to replace the reg. If im wrong and in fact it was one of the later models, then where the fuel return hose goes into the reg there should be a large black clip which locks in perpendicular to the reg housing to hold it together. Remove this clip to disassemble and remove the reg.
If its the first option, then you'll need to remove the plenum chamber first to remove the fuel rails. If the second option, it can be done with eveything in place without removing anything else.
Hope that helps!
Cheers

My symptoms were when it was meant to be off, fuel was still coming through a tear in the diaphragm inside the regulator.
