I thought I had narrowed some rough idle and running rich problems to the fuel pressure regulator. I replaced the regulator with a slightly different one that has the vacuum line from the side and the truck ran beautifully for like 5 minutes and while idling it down some it died and hasn't started since then. I've got 12 lbs while trying to start it. Does anyone know if there's a difference between the two styles of regulator? or could I be overlooking some other issue?
