Sorry for all the confusion on this. My setup question was about setting up for instrumentation. Dan is correct my original question was which might be better to plumb to for cockpit monitoring, metered or unmetered fuel pressure, not how to set up the fuel system per se.  The Garmin EIS accepts a Fuel Pressure value, and as I now know unmetered, so I have to monitor it or I will be flying with an Alert and Red X.
