i have an 05 lly and i am trying to figure out some sensors that are in my way lol the first sensor is on the drivers side fuel return line. it is right beside the turbo at the junction block setup. is that the fuel temp sensor?

next is the sensor that is attached to the main wiring harness latch connector mounting bracket. it is just clipped onto the mounting bracket and i am wondering if i can move it around or if it needs to stay where it was originally??

Reason for the questions is i am trying to tidy up the fuel lines that run all over the top of the engine. I bent up a new cp3 feed line from 3/8" SS and then have the bigger CP3 inlet fitting with 3/8" rubber hose.

Just wondering if anybody can enlighten me on the sensors and their function

Not sure what you are talking about on the first sensor. The relief valve is at the end of the rail and the glow plug controller is in that area.

The one on the bail bracket is the BARO sensor. Move it as you want.
