Blackcoug caught the problem you need to cover the hole above the throttle body up you are drawing in unmeasured air which will clip the fuel maps making the car go into open loop which is really rich to save the motor. The fuel block does not have anything to do with the MPG it does exactly what it should do maintain 40 psi but once you fix your TB by putting back on the taurus TB you will be back up and running smoothly.

Sorry for not making it clear, but the SVT TB was on for about a minute to test fit it. The 3.0 TB has been and will always be on there when I'm driving the car.
I need to know now why I'm getting fuel in my UIM.
Still running rich...
