First I want to thank everyone for their responses. I do have the SID from Continental, I also have Fuel Flow and Fuel Pressure displays on my Garmin 900. My issue is the Garmin fuel pressure values for Continentals are unmetered and therefore taken from the unmetered side and not the flow divider. I didn’t realize the Garmin software values could not be changed in the field for pilot preference when I made my first post. As a result, when originally setup for metered fuel pressure from the flow divider/spider I got a constant low pressure warning due to the difference in values between metered and unmetered pressure. Those with Cheltons can change theses values in the field to suit their preference to monitor either value.  I agree that the spider metered fuel pressure is probably a more relevant value, but again I apparently do not have this option with the Garmin.
