Where to mount fuel pressure regulator

It was already painted when I got it. Was told it's a 2006 Ford Mustang color.

Good chance its the same as mine! i got my color off of a 2006 Mazda 3, Ford and Mazda use the same paint, just different codes. My paint code is 32V Copper Red Metallic. I compared the two colors on the computer, and from what I can see they look the same. Does yours have that nice coppery red look when the sun is beating down on it?
