V8 one is, which is why I asked. Not sure about V6, but I dare say you're probably correct. @Fu Manchu might know for sure.

yea just checked and the VZ LY7 or LEO both have same reg on side of module, OE looks like its no longer available or expensive, but for no fuel pressure at all id prob look at the pump, even check fuse encase its blown, if a reg goes u still usually get fuel either too much or not regulated

 

[07GTS]

the pump still feeds the fuel line to the rail just once thats up to pressure the reg allows it out back into the tank to regulate the pressure in the rail

Wonder if this has something to do with their problem

Both V6 and V8 have the same assembly and the regulator is in the tank as part of the pump.

The tank will need to be dropped and the pump removed.

Early VZ had an external filter. Later VZ had the filter as part of the pump assembly in the tank.

Yes, getting OE is impossible. There are kits which are worthwhile for the filter etc, but if you are concerned about the pump, buy another from a reputable brand and chuck away the cheap one that comes with the kit.
