Where is it located on my 2003 s60t? I looked at videos on the web how to replace it. It's a relatively simple fix. The only thing is that when I look at my engine it's different than the video.
Thank you in advance.

 

2003 5 cyl turbo should have a fuel pressure sensor on the end of the fuel rail such as pictured below. If you do have that sensor you have a fuel pump controller or a PEM that controls the speed of the fuel pump. The fuel pump does not run at fuel speed all the time as earlier cars did. If you don't have a fuel pressure sensor - the pressure regulator is built into the fuel pump. Why do you ask? Got a code?
