So, between the regulator and fuel rail is out?  It would make a much easier install.

Thanks,

Chris

 

I don’t know your arrangement, but between the fuel rail and the regulator should be fine; and that is still between the filter and the regulator – right?  My opinion on fuel system arrangement on the Velocity is screen at tank exit – water/sediment separation in the sump tank – FI pumps – high pressure filter (~30 micron) – fuel rail – pressure regulator – return to sump. Having the sensor downstream from the filter gives you a clue if your filter is getting clogged.  Filter should have a flow rating about 50 gallons/hr for the times you might have both pumps on at the same time.

 

All the best,

Chris;

 

If you are using at least 3/8” dia lines, anywhere between the filter and the pressure regulator should be fine.

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,

 

Chris
