Where is the fuel pressure test port on the 2004 Mercury Sable with V6 engine?

Question

Bought the Haynes manual from Auto Zone, and while the book covers the year of my car, the pictures aren't even close. That book is getting returned today!

Answer 1

look on the fuel rail where it splits on the drivers side.

there should be a little can with a vacuum hose attached to it there as well.  This is the fuel pressure regulator.  Next to it on the fuel rail will be the test port with a s***w on cover.

The easy way to find it is follow the fuel line that comes up by the steering column, and follow it to the engine...the fuel line ends at the fuel rail connector where the pressure regulator and test port is.
