Edge Fuel lift pump Pressure gauge

[RoosterXP]

Hey guys, I installed the big line kit on my 08 6.7 (hose from Filter to CP3), I also installed the supplied T to the big line kit, i purchased a snubber, and installed Edge's Pressure sensor which I Daisy-chained to my CTS2 moniter. Everything seems to be working as it should, however I am concerned that my pressure is too low. im reading anywhere from 3.8-5 psi. I just installed a brand new fuel filter too. Should I have mounted the sensor to the banjo bolt going into the Fuel filter? or is it ok where it is?

Ram has never published psi spec's for the 6.7. We only have volume test specs to work with from FCA

Might just be the way it is hooked into the Edge and how the Edge reads. If you have extra filters in-line that may drop your pressure also. Put as mechanical gauge in the port where the sensor is and validate the pressure. Since you have a larger line form filter to the CP-3 and stock from tank to filter that might be the pressure drop you are seeing.

If it never goes under the 4-5 psi you see now even at WOT and full load you are good, you need about 3 psi thru the factory lines to supply fuel for a stock tune.
