It's neither #12 or 14. It's not listed in any images I can find which is what makes this so difficult.
The vehicle is a 2005 997 Carrera 3.6. I cannot find the part #'s for the 3 power steering pump mounting bolts. They are exposed after removing the power steering pump pulley. In the attached picture you will see 3 holes in an upside down U shape behind the triangular pulley mount. I tried my local dealer without any luck.
