Code P0087, where is the Fuel Rail Pressure Sensor located?

Thank you, Joe! Yes, I was able to locate it, but it's buried. Looks like you have to take whole manifold and other stuff off to access sensor for replacement. Simple fix, just can't get to it and the manifold stuff is beyond my skills.

I can fix 80-90% of items on my car, but engine and transmission not in my skillet. I looked at manifold and about 8 bolts to remove and couple others for connected items. But I don't know what else needs to be done. I'm afraid if I get it apart, I won't get things back together. I was told if I remove manifold, I will need to replace all gaskets before putting back together?

If you can give me an overview of the process, maybe it's not that bad. My local shop wants $550 in labor (4-5 hours) to replace sensor (they want $144 for sensor, but I can buy that for $70). $745 total out the door. I'm definitely willing to try myself if I'm confident about what exactly needs to be done.

I've attached a top view of my engine.
