Thanks for the video. I have not seen anyone make a video showing this online and most people call it by the wrong name.

LML has 2 fuel pressure regulators. One of the high pressure pump and the one in the video is 2nd regulator. The one in the video is for low rpm regulation under 1800 and one on the pump is for higher rpm, above 1800

Is that a low pressure line that Is connected to driver side fuel going in between the y-bridge mines leaking I think

FPR on the high pressure fuel pump; the FP sensor relief valve on the high pressure rail.

A believe that is the fuel pressure sensor FPS, not the regulator, the FPR is on the top of the pump itself.

There is a tool for that. Can be changed in about 1 1/2 hrs. without tearing the top end out.

Did you have a fuel leak on the drivers side fuel rail? 2012 is leaking fuel from that area

Thanks, how long in total was it and did you have metal in screen? Is the one on the cp4 harder to get to? I need to pull mine to see if I have a cp4 failure.
