It had a lime green cap and was on the left side of the motor. He said he could "adjust" my fuel pressure for free to achieve the 315 hp Euro-spec output. Never really put much thought into it until now.

I think he was pulling your leg.

Sounds like he was pointing at the EVAP test port.

To have adjustment in the engine bay would require the car to have a return fuel system.

To confirm, I just went to the German ebay site and looked at half a dozen 350z fuel pump modules and they are the same units we have here in the USA.
