Do you have any more pictures of you testing the fuel pressure out? I am lost as to where or how you get the differential pressure, or what it even is for that matter. As far as I know, you test fuel pressure by installing a gauge w/fitting as in the 2nd picture, but your first pic also has me thrown off. What is the correct procedure?
