It was a fuel pressure regulator, which probably started to go bad when I replaced the fuel pump and filters, likely due to the increased pressure strained the 20 year old regulator beyond it's current capability.

Now with the rest of the maintenance I have done, the car runs like a champ.

That 3.8 liter block is one of the best ever made. Had them in the Grand Nationals with the turbo chargers.
