I just checked the pressure reqirements. According to Mitchell online it can range from 30 to 65PSI which is really a big range. I have to confirm something with you. The pressure I just mentioned is for a 2001 ford ranger. In your original posting, you listed the vehicle as a 2001 ford edge. Since they didn't offer the edge in 2001, I have been basing this on a ranger. If I am wrong, let me know.
Now, the manual says the max pressure is 65PSI with the engine running. However, when you disconnected the regulator, you said there was no change. When you disconnect the fuel pressure regulator, the pressure should go up about 5 or 10 PSI. If it doesn't the regulator is bad. Also, when you were checking it with the engine running, did the pressure increase when you hit the throttle? Also, was there any evidence of fuel in the vacuum hose going to the regulator?
Let me know.
