Pressure Relief Valve & Rail Pressure Sensor Torque?

I'm replacing my Pressure Relif Valve and my Rail Pressure Sensor on my 07 5.9L tonight. Just wondering if anyone has any torque specs and if a person needs to use thread sealant on the threads of either? Thanks.

Do NOT use any sealant on either part.
Pressure sensor torque--- 70 nm (52 ft/lbs)
Pressure Relief Valve torque--- 100 nm (74 ft/lbs)
Over torquing can damage them, & cause leaks.

Are chasing your fuel problem or did you find out this was the problem? I'm still searching.

It was the Floor It FCA on my truck. This is on our other 07. The PRV is stuck open on it.
