Is it a oem fuel pressure regulator or aftermarket?

It appears that the leak was effecting the the fuel pressure because the leak was coming from a rubber sleeve on the right side of the resonance tube. On the left side of the resonance tube is where the air hose plugs in from the fuel pressure regulator which is why I think it was reading the fuel pressure so erratically. Once I temporarily filled that leak the idle was dead still and the fuel pressure was extremely steady and consistent. Not sure if I have any other leaks so we'll see how this goes for now.
