Okay, Im going to replace my fuel pump(s) and filter. When I was under the car I noticed another item that looks just like a fuel pressure regulator in line just after the fuel filter, towards the front of the car. Its pretty corroded on the outside and I want to change it. Is this a regulator and is it the same as the one at the fuel rail? I cant find it in the Bently and searching for parts online under FPR’s says "one per car"? Any thoughts?

Brian

personally, I would lose it…I took it off the 87 iS I had because it made a bunch of noise…no issues with that
Remember my sig guys…
I’m just trying to avoid an issue between drivers. It’s amazing what a losing driver might come up with at tech, especially at a National Championship event.
Yes, "performance enhancing" is the big issue.

I was thinking that the eliminating the noise maker was part of the fuel line replacement

So if you replace your whole fuel system with that of a year that didn’t come with a damper, is that allowed?
Also, is running dual pumps (one on each side of the tank) to solve fuel starvation problems prohibited as well?
