On your video "How to Replace Spark Plugs Ford F150 5.4L 2004-2008 | No Broken Plugs!" at 2:22 into the video, there is a fuel rail pressure sensor connection in the center of the video. This connection has both electrical and vacuum. Could you please tell me where the vacuum hose is connected to on the opposite end? I am helping a friend with his truck listed above FX2 Sport model and the hose has been completely removed from the vehicle.

Good morning.

The hose goes back to the intake manifold. If it was completely removed, look for a cap on a fitting for the vacuum hose.

I attached a vacuum diagram but it does not show exact location.
