Does anyone know off hand what size the thread is on the stock fuel rail for the pressure regulator. I was hunting for a fitting to go in it's place to install my aftermarket fuel pressure regulator today and couldn't find one anywhere. I guess a lot of you guys use "Earl's Fittings" but what is the size and where did you get them from (yes, I know there are a million places out there in cyberspace that has them). Wasn't someone on here selling kits for installing AFPR's ?
