I am getting the bugs worked out of my systems and trying to add one thing at a time as not to screw up what is working.  I have a fuel pressure regulator with a gauge on it in the engine compartment.    I am at a point where I want to add  my fuel pressure sensor so I can read the pressure on the EM2, however, I am unsure as to where the sensor should be placed in the fuel lines.  I do have a very convenient place I could put it between the regulator and the Mistral fuel rail.  It seems that would give me an accurate reading, but I am unsure of what all to consider.  So, what should I be considering?
 
Thanks.
 
All the best,
