Question: Fuel Pressure Regulator for the RA

Did anyone try one of these on the RA (or any regulator)?
I was wondering if there would be any hp/tq to gain from this.... ?

We don't have a fuel return system in our cars so I think it will not work.

The manual mentions a fuel pressure regulator for the 2.4 engine. It doesn't say where it is, though. I'm still looking.

EDIT: Found it. It's part of the fuel pump assembly. #8 in the diagram.

Oh...I See, I didn't realize there was no return line...
So we would have to upgrade the pump.. or add an in line pump...Will this actually help out on a N/A RA?
