On a 2009 2.3 duratec where the heak is the fuel pressure regulator!? I was doing a fuel pressure test and wanted to unplug the vac line from the regulator to test that its not sticking but i cant freaking find the damn thing... I tried looking up the part online to at least get an idea what it looks like but the typical parts stores like autozone dont even list one!?!

 

1997 and older Rangers had a vacuum assist fuel pressure regulator on the fuel rail, this system had a Return fuel line and ran with 30-40psi fuel pressure.

In 1998 Ford changed to Returnless style fuel system, running 55-65psi fuel pressure, and no fuel pressure regulator at the engine.

There could be a fuel pressure regulator/sensor in the Fuel pump assembly in the gas tank, but not sure for 2009
