Reply to "Fuel pressure ok?"

#3 in the photo is the fuel pressure regulator adjustment screw and lock down nut. #2 in the photo appears to be vacuum lines that are coming off of the throttle bodies and going to the vacuum supply pod. I don't see the #1 photo, but it looks like there is another line coming from the fuel pressure regulator body that also goes to the vacuum pod. That type of set up looks like what my old factory 1988 Ford Ranger 2.9 V6 engine used on its fuel injection system and it was tied to the fuel return that went back to the gas tank. On that particular system, when the fuel pressure regulator began to  fail it caused major flooding problems with the engine. Without actually being there to look at your engine's fuel injection set up,  it  would be hard to pin point exactly what is going on. It would help if you could find out who built the original system for that car and what tuning mode is being used. From what I understand about those type of IR throttle body systems, they either use Alpha N or Speed Density tuning. I think Lance Nist  from southern California built at least one system like that in the late 1980's or early 1990's. I will bet that someone on this forum knows where he is these days, but Lance certainly knows how these systems work and was a pioneer with fuel injection and other cool stuff for Panteras.
