The fuel line is a single port on the 2002 Boxster S, similarly the 2003 is same. I have no extra fuel return line on the engine. I did not saw a pressure regulator on the 2003 engine itself. I also manually powered up the fuel pump bypassing the relay, the fuel have good pressure. If I missed a fuel return line on either car or engine side I should have fuel leaks? I was surprise no fuel smell of leak detected.

Then again, I’m still learning the Porsche system, my confidence is questionable honestly? I’m winging it as I go, but not reckless.

I think this conversion is more challenging due to the 02 & 03 year of cut off when they started switch between DME 7.2 to 7.8.

Thanks,
XR
