Yeah thanks for putting up with my dumbness. I could just take the car in, but I like to learn as well. If my engine guy was more local I could just drive it in and may do so in the end. Yes I have been trying to find the fuel pressure regulator, so maybe this is it as shown in the photo (the piece top of the gauge?). I did inspect that small tube on the right and that hose is connected at each end. Maybe that's the vacuum hose? I didn't go pulling on it because I thought maybe it was heat wrap secured and didn't initially want go pulling on it. I do have a vacuum test tool, so if that is the vacuum hose I could try pulling it off and testing. I still think its a bit odd though that my PSI drops so fast when turning the car off, because from google searches it seems to indicate that PSI should remain at least for a few minutes. I forgot all about Harbor Freight for tools, so I'm on my way to pick up the heat gun because I figure its good to have one anyway.
