Fuel Pressure Questions
Finally got my EAS fuel gauge installed. I used a 100 psi transducer. Have read normal was between 65 and 50 psi. Mine has been running around 75 at idle to 70 @ 2500 rpms so far on a short trip to town. I did a linear mapping from 0.5 to 4.5 volts. Was wondering what others are reading and are these readings too high? Thanks.

Is this all stock fuel system? Regulated return?
I'm guessing you've done the blue spring for sure with those readings. It's also possible the trancducer is reading a tad high.
Any baseline readings from pre install? Access to a mechanical gauge to confirm?

From what I have read and been told, 75 is the upper limit. At 80 you start putting extra pressure on things and might start to lose sealing where you least want it.

Seems to be, not sure what you mean by regulated return.
